Here's two of many possible examples of bad customer service:
1) I was buying bear spray at Sportsman's Warehouse.
"What's the difference between that package," I said, pointing at one, "and that one?"
"Well," said the unhelpful staff member, "they're different brands."
2) My manager ordered Potbelly subs to be delivered for our meeting. When they were 20 minutes late she finally called to ask what had happened to the order.
"You're on Dupont Ave.," said the unhelpful staff member. "I don't know where that is."
So you just won't deliver the order?!?
So nice, I bought it twice
