Of course! - I am a firm believer in the 'regular place'. Drives some that I know nuts, but I like to go to the same couple of places, where I know it will be good, everyone knows me, and I them.... I have no interest in exploring new places, but then I am a hobbit through and through. ;~D
Being a regular though, I get to see the regular waitstaff on good and bad days, some days they are on top of their game, some days, they are dealing with troubles like the rest of us.... I tip them the same usually, because I can dig it.... If I were new I might think they were always scattered or didn't care... But I know them.... a good tip on a bad day for someone might turn it around for them in some small way. I wouldn't feel that way about a stranger at a place I've never been.
