A "no" won’t be accepted! The Chinese will never say they don't like something or can't or don't want to do something.
And that is exactly what they expect from their counterparts. This means that if a Chinese event planner asks for a meal in the Bode Museum and this is not possible, then under no circumstances should you answer with "No, that's not possible". Instead, politely confirm that you will try your best and then perhaps offer something else. This is an important expression of courtesy and appreciation. You should also give them your business cards with two hands while looking them in the eye for a few seconds.
And always smile!
