Week 3 Question

I have had friends ask me for free things. That is definitly a position that I didnt want to be in. What made even harder is when people say"so-and-so" gave it to me for free, and i'm like well I dont want to lose my job. And alot o fpeople get mad when you tell them that you can't do it. I just do not understand why people come to a shop empty-handed and expect to get something free!! I've handled this situation prettty well in the past. I am going to handle this situation the same way in the future.
