Pren was incredibly helpful with my odd request! The other gentleman that was working at the counter, looked like a manager was less helpful. While Pren was in the back helping package my item, he said some negative things about Pren to me and the line of customers behind me. It was incredibly unprofessional and I was appalled to see what appeared to be a manager be borderline verbally abusive to an employee in front of customers
