Bud light is a giant worldwide company. Primanti is a regional small chain restaurant/business. Bud Light could lose Primanti Bros total net worth in 1 day and they wouldn't even notice it. Primanti Bros would be well served to handle a situation like this differently next time around. I know it sucks having TDS but the higher ups have to take some meds and realize they are in a pretty heavily Trump supported area. Best served not to piss them off if they are buying your mediocre sandwiches and french fries.
And yes, I eat there one time and was not impressed.
