If it is a strange customer, there is no spending power is cheap, you can give different degrees of gifts, for example, on a fruit plate or snacks and the like, the attitude should be good, tell the guest that the cost of the store is high, in order to give him face, just send more things, by the way, you can also lose no time in giving preferential cards, or vouchers and other benefits.
