What your customers are trying to do
Regular clients and walk-ins want to book a cut.
A barber website usually has to handle booking with barber choice, gift vouchers and photos of recent cuts.
Booking with barber choice: regulars want their usual barber at a time that suits. Show each barber's availability and say whether walk-ins are taken.
Gift vouchers: vouchers suit gifts for regulars. State which services vouchers cover.
Photos of recent cuts: new clients choose on style. Tag photos by barber so clients can pick a style and a person.
