Not a good experience. One star is being generous....

Not a good experience. One star is being generous. Very busy Sunday.. and understandably understaffed, not really employees fault. HOWEVER... after standing in one of the three lines for a minute..she told us she was closed. We moved to the next line... waited over ten minutes.. got to where we were next.. and she tells us... i'm going on break..go to NEXT line...???? ONE line open? Where did customer service go... and common courtesy? Will not go back to this location!
