I quit going to Subway when they changed their whole menu. I went and asked for a spicy italian, blank stare from the employee, "uh, that's not on the menu". I said "Okay" and left. The menu wasn't structured to "make your own" thing not on the menu. Subway was never spectacular food but serviceable, quick, and fairly inexpensive. Not the case anymore, and the weird shit they've advertised lately looks awful. FFS, ad are supposed to make things look better than they are, so if these ads look better than the real thing, it must be dreadful irl.
No, they were (presumably instructed to be) really weird about orders, after they changed the menu.
There's a subway at work, I go 1-2/week, had been the same staff for long over a year when it happened. I asked for some chicken sub with a different cheese than the one on the menu, or something to that effect; was told I needed to get the 'build your own' to substitute.
After that silly nonsense, I realized you could do whatever customizations you want when ordering in the app +use coupon codes repeatedly.
Yeah no, still never had that happen to me. They always ask what kind of cheese I want, any veggies, however I want it. I go to subway frequently, and many different locations. Try a different one.
