It's seen in the video that the customer wears a t-shirt with a TRUMP print on it
so that must have triggered the employee's meltdown in the very first place.
differ from another one.
But all I can say is "Respect" with a capital R!
Respect everybody's opinions or choices.
And if you're working in a store, you have no right to refuse any customer
just because he supports somebody you don't like or hate.
That's not fair, and that's not good for business.
when you get mad or angry and yell too much at the same time,
you could end up very popular on social media or YouTube,
because somebody might be quick enough to take footage of the whole situation,
and then that will be the end of you!
And that's exactly what happened to this store employee.
