I'll bite since even though there's water, I'm working today.
I don't guide on the Ark, and "down here" we save the D-bag award for a company in particular, but I prefer to call them out on the water than on the Internet, so I'll leave it at that.
Back OT, I spent about 6 hours (due to a delayed shuttle process) at the Gorge put in last summer and watched several different companies run trips with hundreds of tourists. Every single one of them was polite, if not friendly (they were busy), seemed knowledgeable and professional, and efficient.
An outsider's point of view for the record.
