Perhaps part of the problem, FCOLover22 (welcome to the company, by the way!) is that there really is very, very little time to do anything on our "nightstop" trips.
I'm Ex Gatwick, as is Paddy, and the Orlandos (Ruby Tuesdays) and Tampas (Blue Martini) that you've highlighted really offer very little opportunity to do anything in the evening after arrival other than have a nice drink and socialise with your colleagues.
Might I ask, without any intention of sounding rude, whether you're British? We Brits love a drink. It's our way of socialising and dropping barriers. The Brits are also a very kinda un-welcoming people (sounds a lot worse than I mean). I mean that we all have our groups of friends and we're happy with them and perhaps make little effort to broaden said group. But, given a couple of drinks (not to the stage of drunkeness), the whole world is our friend!
It's just a cultural difference that we have to deal with at British Airways perhaps more than at any other airline.
We have more nationalities of people working for us than any of the other "legacy" carriers in the world (other than maybe the Middle Easterns, but I wouldn't really call them "legacy" carriers). Every trip I go on, I'm first in the bar with the intention of being last out. I drink moderately, sensibly and ensure that I'm fit for work the next day - but at the same time I have an absolutely great time with my colleagues.
Upon arriving for pickup the next day, I'll speak to my Italian or French colleagues on the flight (not saying that NONE of them come for a brewski, it's just the Europeans tend to come out far less than the Brits) and hear stories of how they've sat in their rooms watching telly for the past 24 hours. The rest of the crew will have built up a great rapport and will have to work extra hard to ensure that those who didn't go out for a drink don't feel left out of the new "clique" that's forming.
The four day TPAs at Gatwick are fantastic! Of course, there's drinking to be done. A night out on the day off with dinner and drinks at The Green Iguana is fantastic, but before that a day at Busch Gardens is a MUST! The only socialising that we do at BA isn't drinking. Granted, a lot of it is, but that's not because that's all we WANT to do, it's because that's all there's time for.
