How to better communicate with foreign guests in English (I'm going to work in a bar soon)

I worked in a bar in England. The key is to remember the names and prices of drinks/wines on the menu. You are very skillful and confident in mixing drinks behind the bar. If you act quickly, they will check out soon, so your income will increase.

You can generously say:

Hello/hello, what would you like to drink tonight? or

Would you like to have a try?

They're going to start ordering wine. At this time, it is time to test your hearing. If it's noisy around, ask for forgiveness loudly? Or should I ask you to forgive me? No one will care too much about your little mistakes or discomfort. The key is to hold your horses and don't panic.

For example, if someone orders beer, you can easily ask them if they want to try the new products in your store, or if they order cheaper than them, but the profit is high. Whether serving foreigners or fellow villagers, we should look at the boss's face and try our best to help the shop make more money.

In Britain, office workers or college students often go to bars to drink heavily every night or weekend. Foreigners who want to find a one-night stand in China are temperate. It's all vulgar in my own country, but it's all fake in other places. You don't have to look up to them. Just treat them as ordinary customers, and we don't have to neglect our customers in China. Our local gods are more noble. If you can kill them, you are welcome. Because.
