The first time that I got a manicure or a pedicure, there was irritation and bleeding.
There was two thoughts on why... My fingers and toes aren't used to it .... or, the person doing it was too rough.
When it comes to tipping, remember that it's for doing a good job. I tip like I tip at a restaurant, 20% typically (+- according to the quality of service). If you start out giving +50% for getting cuts and lousy polish, you've set the precedent of tipping high.
Feeling comfortable in the salon you visit is important also. If you return there, point out what happened and see what the next one is like. They are meant to relax you and give you that pampered feeling that we girls love.
Oh, and polish... if you think it's dry, you probably need more time. 1-2 hours is what it can take. Using a fan helps.
I touch them with my tongue to see if the are dry. Though now I have them use shellac polish, they are dried under a UV light. They previously applied builder gel and the polish is put on them for a very pretty look. When I need a redo, they just sand off the polish (no soak), fill the builder gel, then new polish. Hard and durable in minutes
