How do hotels collect customer information?

Wait for the guest in the lobby and ask the front desk to give you the guest's pre-departure information. When the guests check out, they go up to chat and ask how the service is and what suggestions they have.

It's best to go to the restaurant, which is the best place to get information about the guests. That's the most relaxing environment, otherwise go to those places in the lobby. It is best to go up when they are alone. Otherwise, it would be presumptuous.

More accumulation is enough!
