We (engaged roomates & myself) were at McD once. The girlfriend is HIGHLY allergic to mustard. Think anaphylactic shock & hospital visit from a single mustard seed.
So we place our order. I wanted a big mac, he got nuggets & she got 2 kid's cheeseburgers NO MUSTARD.
Got the food, mine was okay, too much lettuce as usual, but still ok. Girlfriend opened her burger (like she always does, cause she's paranoid, with good reason) and there was mustard smeared all over it. BF takes it back to the counter. Keep in mind, this guy is HUGE, 6'7", 270 lbs, wears a size 16 shoe. Big. He walks to the counter and stands there. The manager walks past him twice before he realizes that he's there about a problem. BF explains the situation, GF is allergic, needs new burgers. Takes about 2 minutes to get her a brand new burger. With mustard. Again. So before BF even opens his nuggets he's at the counter for the second time. Again, waits patiently for someone to ask him whats up. Explains... again, what the issue is. Very polite, calm, collected.
Finally gets the burgers with no mustard. Brings them back to GF and takes a huge bite of a chicken nugget. RAW!!! Gag!
So he heads BACK to the counter. Again he stands there. The manager walks by once, twice, three times. At which point the tall, evil looking BF EXPLODES and says "COULD I PLEASE SPEAK TO A MANAGER ABOUT THESE RAW "BUTT" CHICKEN NUGGETS!!" All 6 people who were in line about to order, look at each other, then turn and walk out.
