It mainly depends on which department you are engaged in. Some departments do not have to face customers specifically, so it does not matter much. A scar of 4 to 5 centimeters is considered relatively long at the tiger's mouth. But if your scars don't cause people to panic, it won't be a big problem. When hiring hotel employees, they will consider or require that there should be no scars on exposed parts of the body, mainly because they are afraid that these scars will affect the mood of the guests.
