After attempting to order a Veggie patty 1/2, the Manager got frustrated because Ms. Amanda, wasn't listening and thought I said pepper when what I stated was banana peppers & black olives. She got pissed off, snatched the tomatoes & cucumber's off my sandwich that had pepper on them. I immediately stated that I didn't want the sandwich if that's how she was going to prepare it. She stated "Fine I can deny service to anyone" ; which threw Me off as I just stated that I didn't even want it. There were multiple witness's two ladies and a gentleman that decided to stay & wait for the police, as I called them when she started cursing Me & then told Me she was calling the Police. I just so happen to be off duty myself, went outside contacted College Park Police, made a report & will be filing assault charges as I was verbally assaulted along with others that stepped in to state that All of her cursing & antics were not necessary. From My understanding Amanda (Manager), Danny (cashier) & Harry are used to giving this type of service. It is totally unacceptable and I will be filing necessary documents.
