Half Protein With Coupons?

At my current location I keep having massive issues. When I buy subs, they’re great. However, I noticed that whenever I use coupons like buy 1 get 1 at a discount, I get half the normal protein in every sub. For example I ordered a Philly cheese and there was such little meat I could see the bread underneath. I also got the hotshot italiano which usually has a bunch of meat but I only counted 4 slices of salami, 4 slices of pepperoni, and 2 slices of provolone in the entire footlong. Is everyone else having this problem??
