When should a barber refuse service?

A barber should refuse service if the client is under the influence of drugs or alcohol because this condition can significantly impair the individual's judgment, coordination, and ability to communicate effectively. Providing a service under these circumstances can pose safety risks for both the client and the barber. It can lead to misunderstandings about the desired outcome, increased likelihood of accidents during the service, and the potential for dissatisfaction with the haircut or style due to the client's altered state of mind.

In contrast, requesting an unusual hairstyle should not result in refusal unless it poses safety concerns or exceeds the barber's skill level. Being busy with other clients is typically managed by scheduling or informing the waiting client rather than outright refusal. Lastly, a new client should not be refused service solely based on their novelty; the barber should take the opportunity to build their client base and demonstrate their skills.
