Event Fee on prediscounted price or discounted price

[jyeh74]

I am in CA.  I am planning an event.  They are charging me a 20% event fee ontop of the original price, not the discounted price.

When you buy something, and say the original price is $10 and the sale price is $8, you pay taxes on the sale price of $8 not the original price of $10.  So why would the event company charge you a 20% fee of the original price instead of the discounted price?

They are also saying they need to charge taxes are ontop of the original price + event fee, not taxes ontop of the price.  Are service fees taxable?
