I would’ve walked out of the restaurant, fallen to the pavement and acted like I had been food poisoned as a little treat for any potential incoming customers...: )
Better yet, drink a little ipecac syrup and throw up in the place.
That reminds me of a little joke one of my cousins liked when I was in high school, it went like this, “Hey, I know where you can get a job.” “Yeah, where’s that?” “Standin’ outside the doctor’s office, makin’ people sick.”
