Use restrooms in departments stores like JC Penney, Sears, Macy these usually are close to customer service areas in very visible high traffic areas. When we are on long distance car rides, we choose McDonalds or Wendy's, I always use the handicap stalls if I have one of the kids with me so I can get us all in there. Pepper spray does you no good with the kids, because your hands are always busy holding them or some gear. So decide ahead of time what restrooms you will use in the malls or on the road. Always go before you leave the house and limit drinks for the kids.
