My complaint:
Ordered a half pound beef-n-cheddar but the sandwich came with no cheddar cheese or roast beef sauce. It was just a bunch of ground up meat on a dry bun. And the last time I checked, roast beef comes thin sliced, not ground up like dog food. Very disappointed.
Suggested solution:
I'm not likely to return to that particular restaurant but you might want to fix these issues before anyone else decides to do the same as me.
