yep, that's exactly what I do. so what if it's the owner who serves me? it's appreciated, and often times will reflect in the service or treatment I get when I return. in addition, I tip bartenders heavily. that way I never, ever have to wait for a drink. at my usual hang out, they always get a drink ready for me when they see me pull into the parking lot, and have it sitting at my usual seat as I walk in the door.
if I ever receive crappy or rude service, I tip little to nothing, and I never go there again under any circumstances.
