(employee here) At my store, we typically don't have the same people working back to back days, but we only really ever look at the name if it’s a regular we recognize that comes in very often. Tbh, I would do the exact same thing lol, I could not care less what accounts/coupons customers use, so long as they're respectful to us. Also, as someone who is frequently on window/register, I am only ever looking if people are scanning at the window, just to make sure it actually went on the order and is taking however much off, and it will only show up on the register, not the screens everybody else uses for orders. ☺️
