    I really like Five Guys and I respect everyone when I go there so I would really appreciate it if I get some of that respect back. Today I went there and there is this lady at the register she was rude, rushed me the whole time, and gave the wrong order even though I told her what I wanted 3 times. Sorry, but I won’t eat there anymore . Note: everyone else that works there is extremely nice and friendly.
