McDonald's

Can’t complain about the people.
Individual personality types may vary.
What I don’t expect to vary is the taste of the food and the service provided.
Can’t complain about the food either.
However, as for service/process, I will typically have to inspect my own order from the drive-through as paid-for items are missing 40% of the time.
What frustrates me, is that people have a screen in front of them to ensure the entire order is bagged.... A 40% failure rate to successfully include all items from my order is way too high a failure rate for a food chain with such great consistency otherwise.

Typical McDonald's restaurant, it underwent a redesign to make it have a more modern look. Also, the food takes a good bit of time to be served if there is even the hint of being busy. A positive however is that the staff is typically friendly and the wait can be expedited by using one of the electronic kiosks to order food.
