University is a big social platform, so there are many kinds of dinners and parties. From time to time, there will always be dinners between large groups and small groups, large organizations and small departments. And the cost of these meals should be shared equally by everyone. After all, in college, except for a few people who have their own extra money or part-time jobs, most of them are given by their parents. Many small gatherings, such as those between brothers and good friends, can be said that it doesn't matter whether guests are invited or not, but gatherings between large departments and societies are mostly funded by big guys unless membership fees can be reimbursed, so it is appropriate to collect money.
But in other words, some expenses are unnecessary, and those organizers have to share them with everyone after adding them themselves. I don't think this practice of compulsory collection of money should be advocated, and it should not be compulsory. So we should distinguish between what should be divided equally and what should be separated. But in any case, these compulsory charges are still not desirable.
But then again, most of the party expenses should be funded by the same company, so if you attend. Others or organizers don't charge you much. If you think it's too much, you can not participate, so there won't be so many contradictions.
In the end, I still don't think we should hurt our feelings for such small money. After all, harmony is the most important thing, and friends still have to do and communicate. If you make things clear and ask clearly in advance, there will be no problem.
