“Mustard wasnt a choice of condiments on the burger, and you CANT have a burger in Texas without it!”
That is a real regional difference. Here in the northeast you NEVER get mustard on a hamburger (although I suppose some might put it on, I’ve never actually seen anyone do that).
Driving down to VA with my kid when she was in school there we stopped in South Jersey for a burger and got mustard on them. She said “oh yeah, I forgot, we’ve already crossed the mustard line”. Even though NJ is not a big state, South Jersey is sort of already a different part of the country.
LOL! I like that....the “mustard line”!!
