In a dilemma

I went to Singapore for sightseeing in August - Singapore is a beautiful city. The people of Singapore is are nice,They are polite, and kind and helpful. Most of them can speak English and Chinese, but also a few people only speak English. I went to afast food restaurant, where the waiter is can't could not speak Chinese. I felt stupid, because I didn't know how to order in English. So I want to stady English, then maybe I will tell him "I'd like to a take-away hotdog to go!" <em>(your 'to go' is fine, just making sure you know it means 'take-away')</em> next time!
