$300.00 for BEER!

Can anyone please tell me that it is absurd to pay $300.00 for only beer at your baby shower? This isn't including juices, waters, and sodas. I think it is way too much money to pay for only beer. This is how much money my husband wants to pay. But I am not agreeing with him. If it was up to me I would buy no beer. But a lot of people that do drink are coming to my baby shower. So I don't know what to do.
