Stop in for a cup of coffee

Customer came in 5 mins before i close.. i hate cunts that do that.. but i was nice.. she didn't understand simple words so starts yelling at me, i stood there calmly with no reaction.. so she starts crying...
P.S. she runs her HOA in her neighborhood..... sooo.. yeah... glad i avoided living with people like that
Customers like that you really don't need.
