There are twelve types of customers, each with varying levels of tipping and patience:
TYPE - CUSTOMER Good tippers and impatient - Businesswoman, businessman, bride (pink dress with tiara) Average tips and patient - Woman with brown skirt, man with grey pants, prom queen (little pink dress), male student Average tips and impatient - Female student Bad tips and impatient - Punk boy and Goth girl Bad tips and very patient - Grandma and grandpa
-At the start of the game, save money to hire a hair washer and hair dryer. The coffee and a barista is kind of useful to have when you are having difficulty. Get the as many extras as possible as soon as ossible (for example, an extra hair washing chair, extra waxing station, etc.)
-Buy the candles as soon as you can since they are very helpful with impatient customers.
