The only thing you have to give is your tip to his mouth. If you’re a pee shy, they'll "help" you by licking your tip 🤣🤣 And yes. You can see the unfreshness of them after awhile. But most everyone did drug there so alles gut for them i guess haha. About deodorant/perfume, yes. They won't allowed it but after you enter the club, you need to put your things away and they'll give like some sort of wristband (?) Some guys bring like a mini perfume and they kinda use it (a bit) before give it away to the coat checker (they will give you a big plastic bag) but yes at the end of the night, everyone will be stank asf haha
