Horrible attitude from a supervisor

As a frequent buyer over a long period, I was highly upset by a horrible attitude I encountered from a supervisor named Anna. Shouting at us in front of the customers, only to find that she was actually the one in the wrong. <br> I really like the store, but I'm weighing my options as to which store to visit, the next time I go grocery shopping with my family<br> <br> Very disappointed and highly upset...
