Lol... Well, in that respect we're different:
a) I'm not a big drinker (alcohol isn't the be-all-and-end-all of my holiday), so am not 'desperate' for a pint, simply because I'm at an airport about to leave on a flight, and b) because the chances of getting a decent pint (of something I'm interested in drinking) at an airport bar are almost zero! Especially when I know what's still to come with all the stress and hassle of going through the same procedure again when arriving at my destination!
In that respect, I'm perfectly willing to wait a few hours, until I'm at the hotel, and can genuinely relax, then go to the bar and (hopefully) drink something foreign (local beer) that's a bit different from the usual shite sold back home!
Marco.
