In my opinion, the opening of my buddy's "Wonton Pingdian" should be a "send friendship". What does "send friendship" mean? We can think of it this way: what a store needs most when it opens is popularity. We should attract more people who are close to it to join in. The boss is most happy because of its popularity and excitement.
If you don't go for nothing (empty-handed), you must prepare gifts. I don't think you need a high face value, just an atmosphere! Since it's time to bring in some "close friends", don't let them pay more. It's better to be cheaper.
Just send a pair of flower baskets. Putting it in front of the store that day can add festive atmosphere, think of better greetings and write more names (don't feel shabby, some people may think there may be "extra" gifts ~ ha).
Popular, your good buddy will naturally be happy! The number of gifts is not an indicator of "rich financial resources"!
