Here's some ideas for you to use:
- Wear only lingerie/costumes available in the shop whilst working
- Wear a remote vibe, leave the remote out with a note stating vaguely what it does
- Have a set toy each day that customers can try out on you/watch you demonstrate
- Become a maniquen for lingerie in the window for a set period each day
- Wear a sign/write somewhere visible 'Just ask to see more of my body'. Flash anything a customer requests
- Have at least 1 orgasm each day in store whilst the store is open
- Give out something to every customer you serve - depending on how far you want to go, it could be a nude pic, a coupon for a bj, or whatever else you can think of
- Spend a set length of time tied up/blindfolded in store each day - ideally with a free use sign or similar
- Take a marker in each day - offer each customer you serve a chance to write on you
Feel free to take them/leave them/modify them as you like
