Just had the worst customer service interaction in a while at Cervantes Coffee.

I'd never been to this place before and I know some people on reddit had recommended it. I was in the area so I stopped by and went up to the lady at the register and just asked what syrup flavors they had and she responded "regular". And I was like okay... so like... vanilla? "Yes." And... caramel? "Yes, yes, regular syrups." So it was clear to me at this point this lady was frustrated (I guess?) that I was even standing there which made me feel uncomfortable, so I just looked at the menu for a moment and picked something and went to insert my card and she said "you have to tap", I responded my chip is worn and only works when inserted and she scoffed very loudly and just walked off. So I was just standing there at the register looking around and another employee had to come up and finish the transaction. Like... dude. What the hell? Having worked retail for 10 years I fully understand the bad days we have, but why are you taking it out on someone just existing in your coffee shop not causing a problem or being rude? I'm curious to know if anyone else has had this experience at this shop and if this is a regular occurrence? I mean, regardless, I really doubt I'll be back again lol.
