I'm thinking of yelling at the shop because they delivered the wrong sub.
Do they get your order wrong often?
It seems like they never get it right.
I know it's frustrating to get a wrong order, but you shouldn't yell at people. If you're not satisfied, you should order from a different place.
What if I lose my mind and yell at the staff.
If you can't control your anger, you might want to seek professional help. You probably don't want to be the type of person that yells at others over small things, right?
