The pair probably did it very often, walk into a hotel and give a number and get away with it. Takes me back to a shonky bloke I used to work with years ago, him and his wife were sort of trendoids, you know up themselves a trifle and their favourite entertainment was on a weekend head into one or two of the big flash hotels in Sydney where Americans and the like stayed. And in the bars and foyers, lounges intermingle with that type of guest, giving them recommendations where to visit, eat, etc and of course being shouted a few drinks. Of course many of the Americans loved to talk to Aussies even if some of it was BS, lol.
Bizarre sort of entertainment, but each to their own.
