Any good mones for tipping jobs?

I know this is a strange question but my buddy wanted me to ask. He works at a bar/lounge and makes tips, obviously. he was wondering if there is any mones that would help maybe increase his interactions with the guests. I recommended IO and IH. but was wondering if I was on the right track since I am pretty new to this stuff myself. Any help/info would be great.

Yeah IH…is pretty damn good…as a former waiter for 7 years in NYC, connection with the customer does increase tips…however, I found that the MORE friendly i was, the LESS of the tip…I always got the GOOD tips when I was percieved as important and just did a great freaking job. So I’d say IH & A314.

Ishine and IO is going to gibe you the best happy-I can talk to him/her bar vibe. Add some ammo and you get the sexy I really like that guy and I can talk to him bartender vibe.
