Re: hookah and money
In regards to Coyotero. Thats generally a safe bet. Although it sounds like in this particular case its not necessarily a "once in a while" thing. It sounds like people expect him to bring and provide a hookah, which crosses that boundary a bit i think. it also sounds like its the same people, so if you buy in bulk, they'd be able to enjoy it in the future rather than just 1 night.
This is a lot of assuming, so please correct me if im wrong. I agree with coyotero though. If you choose to bring your pipe on your own, expect to cover all the costs. It'd be like it go over to a friends and bring a nice bottle of single malt scotch and ask for them to go halfsies :/
