I would like to purchase the book for Sociology 130. May I see your student ID? I didn't know we needed it. Please go get your ID, and get in line again. But I waited in line for two hours! I'm sorry, but you need a student ID to purchase textbooks here. Are there any other options? Show me proof that you're a student at this college, and you'll be good. I have my report card. Here it is. This will do. Nice grades by the way. Thanks! I worked very hard for them. Good luck with this semester.
