The term for the strategy of waiting until the foodservice employee puts the first portion of meat on your sandwich/burrito/whatever to ask for
double meat. That way, the size of the first portion isn't compromised by the knowledge that a second portion is coming, and sets a
precedent portion size for the second portion, avoiding any size
discrepancy between first and second portions. Particularly effective at Chipotle.
Employee - "What kind of meat, sir?"
Fat Guy - "Chicken, my man."
E - *Scoop*
E - "Any vegetables?"
FG - "Actually, can I get double chicken?"
E - "Godfuckingdammit okay."
FG - "
Fat Guy Strategy wins again."
