I went into Wendy’s the other day around 9:00 p.m. I was the only one in the store. I ordered a Frosty. The guy at the counter pushed the little button on his register and leaned into the microphone and said “Frosty”. He then proceeded to turn around and draw the drink HIMSELF!
I asked why he used the mike, and his response was, “That’s the way I was trained to do it. If I don’t, I get confused”.
