Car needing to run because temps are so high the a/c needs to be on or not, I can't fathom a genuinely good reason to leave your baby in a car unattended in the parking lot of a 24 hour adult XXX store at 10:30pm on a Sunday night.
For those not in the know, there are generally two types of adult stores;
The ones that don't have private rooms or "arcades" in the back and those that do. In 2019, there's not anything being sold at those types of stores that can't be purchased or freely obtained online, the only exception being the "arcade rooms"
Market Video & News has such an area.
Do a Google (or Google Maps) search for Market Video High Point and expand the Q&A section to view the types of questions being asked about the "activities" there.
Not an appropriate parking lot for a baby/toddler regardless of the reason for the trip, IMO.
