Many busy, high end salons do give you another appt day and time when you pick up. Its supposed to be for your convenience, and theirs. Less phone calls to answer, and you dont have to wait 3 weeks to get in when you call. It is nice of them to offer a discount. I do not discount. I do find asking or even mentioning a tip, whether in signage or not, to be unprofessional and rude. However, signs are readily available from grooming suppliers to encourage tipping...I would never have one, nor do I mention tips, EVER, to a client. I would suggest you talk to them before making a decision to move on. Tell them you want X amount of weeks, and ask what the price will be. If after talking with them, and you are still unhappy, move on. I would suggest you dont burn that bridge tho, as you may want to come back in the future should you find that you arent happy with haircuts etc elsewhere.
