A local chain pizzeria.
DH & I get delivery & take-out from there quite often, and they rarely goof. On one occasion, the delivery guy forgot our dessert, and went back to the store and got 2 for us. Another time, I don't remember what exactly went wrong (wrong toppings, delayed delivery maybe?), but we had a credit for a free pizza for next time on our account.
Last night, DH called in an order for me to pick up on my way home. What I didn't know was that he'd also ordered a dessert. Counter guy didn't mention it, the guy who handed me my pizza didn't mention it, and I didn't know to ask. So I get home, and DH asks about the tiramisu. So we call, and DH gets an apathetic counter guy who says we can come back to get either the tiramisu or our $5. Yea, not so much. So I call back, and ask for a manager. Explain to him what happened, including the apathetic guy on the phone. I was expecting him to dispatch some dessert with a delivery guy or something, but instead he reversed the entire pizza charge.
Yea, we're still ordering from there!
