Like to answer, refuse if you don't need it, choose your favorite dessert type if you need it and tell the waiter. The waiter will give it to you.
The receipt asks you to go to the bar to get coffee, remember to take the straw.
Problems and analysis:
1. Go in and order coffee at the counter. Do I have to pay on the spot to get a better seat? Or will the waiter bring it for you?
Going?
Order at the counter, pay on the spot, pick up your coffee at the special pick-up place, and then find your own seat without a waiter.
2. Is the ordering process similar to McDonald's?
Yes, tell him what you want.
3. Can I add sugar and cream? Where can I add it or ask the waiter to add it
There should be a small counter next to the counter to put sugar, creamer, spoon straws and so on. Just add it yourself. If not, then
Ask the waiter for it. Take a closer look, there should be.
4. Can I get a refill for free?
Of course not.
