People tend to check in during these times:
Check in to Taco Bell on Foursquare. Everyone's doing it.
Very slow service.
For vegetarians: If you're ordering food where you substitute beans instead of beef, make sure you check that crap. They are constantly messing up orders at night through the drive-thru.
slowest place ever.
Go inside. The drive through is nothing more than a lesson in patience.
Don't be in a hurry, you may be here a while
Consistently the slowest service.
I thought drive thrus had fast service being a fast food establishment... Guess not
The slowest drive thru ever with a 90% chance of them screwing up your order anyways...
Slowest "fast food" I've EVER experienced.
Bring a sweater, it's freezing in here
