I finally worked up the nerve to hit a drive-thru tonite! (After 20+ years). I took the advice found here and looked for the busiest one I could find.
After ordering and waiting to get to the window, that all-to-familiar feeling of panic crept up. I thought "I can't do this alone". So I grabbed my phone
to call my sister (she knows). I told her what was up, and she helped me calm down, mostly just hearing her voice! Well, it was my turn at the window,
the SA said "That $7.68, ma'am" and I hand her my card. She swiped and handed it back to me,then turned to get my order. That's when she looked at
me through the window and smiled. She gave me the order, and while still on the phone I silently mouthed "Thank you" to her and pulled away.
It was a great experience! Just thought I would share.
