There's also that time during jumuah when the director of the mosque delayed the prayer so much that it started during the time of al-Asr.

That sounds like a pretty slimy extortion technique. Your director has been reading Art of The Deal.

Sounds like you just have a bad mosque. Mine pays a donation hustler like 5k every Layl Qadr to hype up the crowd and he actually pulls 20k+ donations. He holds the most crowded taraweeh crowd hostage until he gets 200k for the masjid.

All these people are used to gov funded mosques in their home countries. They are like a fish out of water, copying what they see the churches doing here.

Every institution has an innate desire to grow. Rather than stay at a sustainable level, they expand whenever they have a surplus and resort to more and more pushy means when to match the previous year, or even their previous year + expectations of growth. It takes genuine self control and backbone to resist this. You need to stand up to the congregation and tell them you won't have free coffee like the other masjids. You need to tell your imam that he needs to keep driving uber on the side even though the masjid has the money to pay him for the year. No one wants to be seen as stingy. These forces exist even in small business, and it's much more difficult to control when you have a whole board instead of a single leader, and they control donated money. They also see nothing wrong with being pushy. Giving to the masjid is good, so they see it as doing you a favor to get you to give away money that you otherwise wouldn't.
