restaurants do repaint and refurbish quite a lot, as do hotels. It's funny how easily people cope with this, as a rule. You almost never hear customers yelling 'What are you, stupid?? Change it back, you Nazi!'
Conversely, customers often drift away from a restaurant that never changes, never does anything new. They get bored with the same old same old. So restaurateurs will introduce changes in the search for new customers.
Perhaps you would get more sympathetic answers if you posted this in Food & Drink?
