Currently I'm at the beauty therapist in John Lewis. I've had a bikini wax and a very nice manicure from one person and a very nice pedicure from another one. What is the etiquette with tipping? I'm paying with gift vouchers and don't have any cash. Would it be awkward not to tip or more awkward to tip with my card or go and get money from the cash point. I've tipped my hairdresser this morning £7 for a £33 haircut but added that to my bill.
