It was my fifth day yesterday and I had a customer who paid in CHECK. Since there were so many guests coming, I was totally panicking and I think I gave back the check to her instead of keeping it. Do I have to keep the check or is it right to give it back? If not, should I tell the LOD duty when I go to work or the HR? What should I say? Will I get fired? Please help! I don't want to lose my job when I'm just starting.
