So had a group of 13 Americans in at our pub. Did table service. We don’t do table service but did today. On a £150+ tab we got tipped 45p. 45 pence. I’m not normally arsed but I ran up and down 3 flights of stairs WHEN WE DONT DO TABLE SERVICE BUT THEY INSISTED BECAUSE THEY DIDNT WANT TO GO UP AND DOWN STAIRS FOR DRINKS only gave 45pence. Fuming😩
