The boss contracted the barbecue in someone else's hotel. I'm the only one in the shop. The boss and his friends ate more than 300 pieces of barbecue. Will it be bad if I tell the boss?

Call the boss secretly and see how to deal with it. As an employee, you should tell boss Li about the situation. If you know and don't tell him, it's a bit bad. Their bills are also secretly prepared, just put them there and show them to you when your boss comes. As an employee, this kind of thing must be told to the boss. You have no right to hide it, let alone give them a free ticket.
