What Happened?!?!

Did any Whataburger in Texas have to stop their 75 cent burger promo? For some context I just ended my shift for today at whataburger and around 2pm managers told us that corporate (or some higher up, I’m not sure) had informed them to stop the promotion for today due to the chaos and the “system going down”. So I spent the rest of my shift informing all my customers in drive thru of the situation some were understanding while some were visibly upset/annoyed (rightfully so). So I’m wondering is there any other whataburger in Texas going to through same thing? Because from what I heard it’s nationwide… let me know I’m curious!!
