Some explanations to support my stance:
Bringing meat into the storehouse allows the church to do ministry, help the downcast, pay staff, etc. I've been tithing since I started working, so it's nothing new to me. For others who are new to their walk with God (and tithing), they may feel uneasy about tithing because they may be faced with a choice between paying this or that bill or tithing.
Churches do preach about faith, and you're right that some churches do need to practice what they preach. Unless a pastor has multiple income streams, some ministers don't take a salary. But for other preachers whose sole income comes from tithe and offerings, well...it should be no surprise why some preachers talk about money so much.
