If you are at a restaurant and its just you and your baby. And you have to use the restroom how do you do it?

I was at a restaurant. Had to change the baby and had to pee myself. The baby changing station didn't have straps. There was no chair in the bathroom. His car seat was in the car. So basically I had to squat while I was holding him😑😑😑 I'm like seriously this is ridiculous.
