First time in my life I tipped 0 !!! Waited 30 mins for our pizza ( no big deal ) recieve wrong pizza , have to wait and flag them down to let them know this and told just a few mins ... 40 mins later I flag him down again he says just a few more mins to my " is that my pizza sitting there for 5 mins " it was .... still wrong but I eat because I'm starving .... no apology... bill comes our $19.00 large meat lovers is now $26.00 because we asked for white sauce instead of red .... guess the ricotta on both our pizzas we never asked for and they messed up is expensive
