In Bangkok there are better money changers than bank rates, best to ask in the CM forum.
100 euro notes are best and maybe some 20 euro notes for the last day and does not need 100 euros worth,
Again in Bangkok the plugs are the round German ones plus the flat USA ones, both in one soclet and 220v like Germany.
Viagra etc can probably be found around tourist area at drug stores, do not buy on the street,
200 euros (10, 000 baht) a day to party will get him a long way, almost hard to spend that much unless he is buying drinks for everyone.
Hope that helps.
