No you do not get paid because they are doing you a huge favor since its a hard career to get into. Although at the shop that i worked at if you worked at the desk or counter they could do your apprenticeship at the same time as you were working so you still made some money.
It actually depends where you get the apprenticeship, most places will not pay you because they are teaching you and spending time out of there day to do it. Some places though may pay you but that is usually if you are doing extra work while you are there.
Nope, your there to learn first hand. There basically giving you there time to help you learn a skill you want to learn. Theres no reason you should be being paid for that.
usually not, because they are doing you a service by introducing you to piercing for free. Its like an internship no pay.
