Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
A nail salon was completely booked at 2 pm for manicures.  Each manicure costs $20.00 per client so the salon made $200.00.  If there are 210 fingers in the salon at 2 pm, and everyone has 10 fingers, how many people in the salon are not clients?

### Response:
 Saluni ina vidole 210, hivyo kuna watu 210 / 10 = <<210/10=21>>21 katika saluni.
Kuna wateja 20, hivyo kuna 21 - 20 = <<21-20=1>>1 mtu ambaye sio mteja.
