AITA for telling the local bartender she brings more business than the other bartenders at her business

So a local bar hasn't been doing well. Today's bartender (we'll call her gee) aw we'll another bartender (we'll call her Kaylee) bring in all the business. Tonight I said gee and Kaylee bring in most of the business. I got kicked out for bad mouthing the other bartenders. AITA for not saying the other bartenders bring in as many customers as gee and Kaylee

For context, another bartender (Cassie) was there as a customer and took offense to what I said. However, this was not a dig at Cassie. I was just trying to point out a fact as a customer, but was silenced for saying something that went against other employees at this bar
