Actually dumbass YOU’RE the pathetic one

I started shopping for this customer and since I had been here all day and knew that the ice cream they wanted was out of stock, which I double checked and it still was, so I asked to see if they wanted something else. They proceeded to tell me how I am an idiot for shopping for the ice cream first just as I am letting them know that I knew it was out of stock from earlier. They didn't care called me a liar and

I immediately go to call customer service to cancel. They continue to shout in all caps for me to refund the ice cream and they add more crap and are getting angry that I don't respond in the 10 seconds that have passed. I let them know I am on the phone and am canceling their order and they proceed to tell me "your pathetic" and now I am going to miss out on a bonus "cash tip" hahahah yeah like someone who would belittle someone else at work would ever have the decency or respect of tipping even a dollar.

Just want to come on here and say that I am sorry for anyone that has to deal with such scum. I just feel bad for the pour soul who will shop their order after me...
