The customer gives you a £10 note and a £5 note. It is Thursday morning and some bath towels due in as a special buy have not arrived in the delivery but are expected tomorrow. The hand towels and bath mats have been delivered. It is 2 PM and a customer arrives looking for the bath towels. They have been hoping to get a set of four for their newly decorated bathroom and approach you looking upset when they can’t find them. What do you do?
