My husband and I get McDonald's drive-thru once in a great while - usually if we have to drive somewhere early in the morning on the weekends. We're going to visit some friends, so we swing by to order a couple of breakfast sandwiches. I order a coffee. The cashier asks if there's anything else. I say "yes..." turn to my husband to confirm his drink order, and then am told my total and asked to pull around.
Ok... So, I ask if I can add in a medium hazelnut iced coffee. Apparently, that will have to wait until I pull around. So, doesn't seem like a major problem, just a bit of an inconvenience - until I got to the window and request the drink.
I suppose she would have prefered I completely forget about the drink, because when I asked about it she rolls her eyes and says "Fine, what did you want" in a really pissy tone. I just repeated the drink order, paid and went on my merry way.
Like I said, not major bad service, but it's frustrating. I have no idea why she was mad at me - she could have easily saved herself the problem of adjusting the order later just by waiting the two seconds for me to finish ordering.
