It's not so bad if there's a mamasan or some equivalent old cunt as a go-between. For instance, in LSS brothel they often have EE girls that are still practicing "hello". But you pays your entrance, get sucked and fuck, pay the bill, fuck off. Simple. Even without a mamasan I've never had a problem without when punting abroad. German Eros centres or big Brazilain brothels, all you need to have and know is the right change and a condom. When you get home, I bet your dog doesn't talk English either, but probably you still witter away in nice soothing tones and the mesage gets across.
For UK Indies, I just smile a lot and have the right change. If she can fuck well, not much difference to a civvy when you are so pissed you can't remember whatever crap she was wittering about at the beginning of the sentence but you smile and nod and go 'hmmmmm... yeaaaah' understandingly as you eyeball her and slide her knickers off.
