Read the following context and choose the best option to answer the question.
Context: A place so classy that even the bathroom stalls had their own mirrors , and crystal chandeliers dangling dangerously over our heads the entire time . Delicate morsels of food , each deliciously rich , were served to us on stacked plates , and our menus contained genteel accounts of this history of both our tea , and the Tea Room . The waitress even attempted to put a folded napkin in my lap , but I took it off her . My little brother had accompanied me there , only to take one look at the prices on the menu and ring up his friend to tell him all about it .
Question: Why did the writer 's little brother ring up his friend ?

- Because the place was very classy .
 - None of the above choices .
 - Because the bathroom stalls had mirrors .
 - Because he was surprised at the high prices on the menu .
