When people eat in a hotel, is it best to ask for a "receipt" or "tax invoice" from the hotel? Why?

You'd better get the invoice you want. First, you can contribute taxes, otherwise the hotel can evade taxes on your consumption. Moreover, most cities now adopt award-winning invoices, which means you may get a cash prize. I scraped out of 50 yuan for the first time, and the exchange quota varies from place to place. Generally, cash below 100 yuan is exchanged at the hotel where you eat.
