The thing I don't like in the US (Kevin)

The most annoying thing for me in the US is that we have to pay some tips. In Taiwan, we don't need to give tips to the clerk after finishing our meals. All we have to do is pay the money shown on the bill. However, there's a huge difference in the US. The final price not only includes the tax, but also some tips. If I ordered a 10$ combo, I might have to pay 15$ for my meal. This unwritten dictate is everywhere in this country. Everything in the US is expensive for a student like me. Without income, we have to do our best to save money as hard as we can. For me, the culture of tips is unfriendly for some international students, but I believe I can get used to it day by day.
