I agree, the guy deserved to be arrested. Though I certainly understand heightened frustration levels, incompetence on the part of a vendor does not warrant violence.
He should've called 911,
like this gal did
Then he could say "He said he are the manager!"
What kills me at fast food places is giving them a complete order, like "A number 4 meal please, medium, Coke, to go, thanks" and then hear in reply:
Would you like the meal or just the sandwich?
The meal please, with Coke, medium, to go, thanks.
What kind of drink would you like?
Um, I said Coke, thanks.
Would you like to super size that?
No, thanks, just medium please.
For here or to go?
