I do. Usually food and drink so they can all sit there and laugh while I use their tools and build my wheels.

In all seriousness my lbs is not "just" a shop to me, it's more a place where a couple of friends happen to work. The wrenches in there are a good bunch and the owner is someone I spend time with off and on the bike.

I've been using the same shop for 10 years (since I moved to Singapore).
