I suggest before entering to the taxi to make it clear with the driver to use the Metter, Anyway  even with a Metter on  if the driver wants to cheat you he'll do it,I remember one time driving to my hotel in silom suddenly the driver took the wrong turn I told him it's the wrong way but he ignored that caused a delay of almost twenty minutes and extra 200 Bht to the normal fare to Silom.

I would insist he stop, show him the taxi ticket receipt and point to the compaints number. Before he can leave that official taxi area, he has to pass through a barrier and give his entrance ticket (remember this includes his taxi number and driver's name) to the guy who mans it. If he has not turned on the meter in the short time it takes to turn on the meter, I'd also shout to that guy and point to the meter. Also you should note that taxi rates have quite recently risen and so the drivers are already making more for airport runs.
SInce BKK opened, I have arrived back in BKK probably more than 100 times. Twice I have been in a taxi with a doctored meter. In those cases I pointed very obviously to the meter and said loudly "meter broken". Even though the drivers might not have understood English, they got the message.  I then took photos with my phone of the meter, the driver's permit by the windscreen, the taxi number on the back left door and the driver himself. One then turned off the meter and said in English "pay usual amount, OK?". The other waived the fare altogether. I suspect he was afraid I'd register a complaint which could cause him problems! But my solutions are less easy if the taxi is hired unofficially from the arrivals area.

Apologies to @DenverDude. There are of course two roads next to each other at the arrivals area and taxis have to be in the one further from the entrances. There are indeed barriers there and one way revolving entrances. But not all are in operation and so it is easy just to wak through these.

it did not , no railings or anything, just normal curb.

Not true - unless it's happened in the last couple of months. You can go up in the people movers, escalators or the lifts.  Years ago, I always used to go to departures up to get a taxi which had just dropped off passsengers. The only problems now are that there are airport cops trying to stop this (not effective in my experience) and the taxi will not be registered for airport returns. At the official taxi stands you get the printed notice with the taxi number and other details. This may (but only my guess) lead to a problem if for any reason you wish to complain about the taxi you get from upstairs.

Yes I do.

Basically you can purchase it at any pharmacy at a small cost and no questions asked.

I presume you understand the potential side effects, etc.
 

I wish you would post the pictures now so that the rest of us can steer clear of him.
btw I'm not very active here but I love reading your posts.

One time I was in India, staying at a luxury hotel in Chennai, the room cleaner on my floor found me on Grindr and we hooked up in my room.  😃

if you chose your hotel wisely only time one needs to cross the street is to go to soi Twilight from Tarntawan or to Jupiter from Raya.
 
Arena requires to cross the street but there are lights and desperate can use overpass at Chong Nonsi BTS . The same  with Senso and SalaDaeng BTS 

either one will do, one night only and you don't get much of sleep if you planning on checking action so no need to spent much money.
 
I'd stay in Nantra Silom in soi  8 , cheap and no problem with guests, steps from Tawan. 
 
For  soi Twilight and Moonlight  you may also consider Suriwongse or Raya

Please report back if you stay at the Suriwongse. I haven't been there in years and would love to hear about it again.

both of you are welcomed

And what happens if one does not have their passport on them?  I always leave mine in the hotel room locked in the safe.
