What I wanted to say to them:
Ok so what if the service is slow? You are with the people you are with to enjoy a nice night. You're still together whether standing in a line or sitting on bench eating. So your complaining is what is ruining your night, NOT the slow service.
But really I didn't say anything to them. (Aren't we all braver in our heads?) Honestly I was busy chatting with the family in front of us and managing my kids who were running around and HAPPY. When I got to the window I realized that I had my bag with CHOOSE JOY embroidered on the side:
Not sure if they saw it, but that's my advice... Just find the joy in the night, even if service is slow. It really is about perspective and attitude. I am going to choose joy.
