Can I get a receipt from Hong Kong and Macao?

It's basically impossible for a big seller who delivers a lot of goods, because you buy too much at a time, and you can't issue receipts one by one, but a small seller with ordinary business can, because there are not many goods to buy. Another possibility is that many people actually don't want a receipt, but only a few people say they do, so even a big seller can find a shopping list for you, get a receipt separately, and pay for all other bills. Personally, I don't think typing separately is a condition of authenticity.
