Cathy teaches you how to measure cup size

One day, after work, Cathy brought you to a changing room with a measuring tape.

"Remove your shirt."

"Why?"

"I'm going to teach you something which will be useful as an employee of this shop."

"Which is?"

"How to measure your cup size. hurry up and take off your shirt."

After a detailed session with Cathy on how to measure cup size of a lady, you managed to do it. Fortunately, Cathy said when there's a lady who needs to get measured, she wouldn't send you to measure because it's just inappropriate to.

"Great job Alex!" Cathy said. "In case you didn't know, tomorrow is La Senza's Day. Julie and I prepared a little present for you. This is your reward for your hard work today." Cathy passed you a La Senza paper bag.

You put the paper bag in your bag and scurried home.
