填空题

John Andrews had to wear glasses ever since he was a small boy. So, shortly before the time when he was to leave school, his parents suggested that he might train to be optician so that he could help other people with their eyes.
John did not have any strong feelings about what he wanted to do, so he agreed and started a course of training with the intention of becoming an optician. He found the work interesting and did not have any trouble in qualifying at the end of the course. The next problem was to find a steady job.
He looked at the advertisements in suitable journals, applied for a number of the situations offered, and at last managed to get one in the town where he lived, so one Monday morning he set off by bus for his new work.
The owner of the optician"s shop where he had been accepted had another assistant and a secretary. The first time that John tested a customer"s eyes, the owner of the shop watched carefully to make sure that he knew what to do, and he was very satisfied with everything that John did, except that John did not know anything about prices.
"We"ll discuss that at lunchtime," he said to John quietly.
At lunchtime, when they closed for an hour, the owner of the shop said to John, "Now, we"d better have a chat with reference to our charges for glasses, so that you know what to say to customers. In this shop we expect everyone to pay a fair price for what he or she gets, so when you have tested someone"s eyes, and they have chosen the kind of lenses and frames they would like to have, and they want to know how much they will cost, you should say, for example, "$54". While you are saying this, you should watch the customer"s face carefully, and if he or she does not seem frightened by this price, you should add, "That"s the price of the frame. The lenses cost $54 more." "If the customer still doesn"t look as if he or she is worried," you should add, "for each lense."" What did the owner want to discuss at lunchtime
______.
