Shell
Premium Platinum
Shell I would always go one of two ways:
A) just go up and say hi, how's your night been? And hope that they are open to striking up a conversation.
B) say something absolutely ridiculous like "that's the best damn hat I've ever seen" and hope that they're playful.
Had about equal success rate depending on the fella. Just go with what feels natural. The worst they can do is say they're not interested...so go chat to someone else
or how about C) ask them to play a game of pool (the place has a pool table). and the whole focus won't be on conversation either that way.
