McDonald's

Terrible. I went through the drive through today to pick up a bacon, tomato and egg wrap with a coffee and hash-brown. I get the wrap and coffee, but not the hash-brown. No big deal, just a minor mistake right?
I go through the drive-through again and they give me the hash-brown I payed for and ask for another for the inconvenience they caused me.
They seem perplexed and confused as to why somebody would believe they're entitled to another after being forced to go around the drive-through another round!
I wasn't even offered a coupon or a voucher for my troubles! It doesn't end there either, the place smelled rancid and the wrap was mediocre at best.
Terrible service, terrible food. A complete disgrace to the McDonalds brand. Avoid this franchise like the plague.
