Smart people understand that politics is politics and business is business. Smart people also understand that the party thing isn’t personal. You can disagree with someone but you don’t treat them badly or harass them in public because of said disagreements.
Stephanie Wilkinson is not a smart person. She’s a dumb person. She thought the presence of a Trump Administration official in her restaurant required her to take a grandiose moral stand. Wilkinson showed no class, while Sarah Huckabee Sanders showed all class, politely agreeing to leave and even offering to pay for a meal she wasn’t allowed to eat.
