Membership renewal guy at Costco gloated to me about Manafort’s jailing. Then escalated repeatedly.
I gave him a piece of my mind.
You should notify Corporate. That person is there to help You as a Customer not to spew political crap at You.
Believe me. Grab the store manager and nicely share your customer experience. Then get out of the way.
Talk to the manager. If a conservative membership renewal guy gloated about Trump to a DemocRAT, he would be fired.
