Capt Bob’s rt 140 in Princton Mass. I think the rudeness is saved for the non customers that they call "freeloaders". The posted signs say things like "directions $5". They attract bikers who like to ride this nice 2 lane road, and they are actually nice if you buy something. Lots of repeat biz I think. They are well known enough around here to sell t shirts that say "show us your tips"
