I usually get a 20-oz coffee. This time I walked up to the windows on the back and told her I would like a 12-oz of my usual instead. I didn't want a 20-oz because it is almost 11am and I just need a little boost and not the entire shabang.
So she hands me a 20-oz. I apologized and let her know I had asked for a 12 instead. The fact she made the wrong size isn't the bad service.
The fact that she continued to tell me I had asked for a 20 while I continued to tell her 12 was the bad service. She even kept arguing with me about it telling me "You must have said 20."... No... I very clearly said 12. Open your damn ears. 20 is what I usually get. 12 is what I asked for.
It really was no big deal at all until she kept saying "You said 20" over and over and at one point came up to say it yet again and said "You said.. you know what... It doesn't matter."
Well it didn't matter until you told me I was wrong a billion times while making the right sized coffee. Now it matters.
