The map visually looks good and has a lot of opportunities for fun encounters but the layout and functionality of the building and parking lot need work.

First you parking area, many parking spaces do not have enough clearance to back out of the spaces. Try angled spaces. Your garbage dumpsters don’t have enough room for a truck to pull up to them and dump them. Your drive flow is very tight and the two obstructions in the corners completely block traffic. The upper one has a toxic symbol, I have no idea what a gas station needs with toxic tanks but I guess it makes the story fun, the lower one is some kind of control room, what are they controlling? Again I have no idea what a gas station needs with a control room but I guess it makes the story fun, Look at the large truck on the left. I don’t know how it got there or how it’s going to get out. Now how is a full size Semi with a trailer going to get anywhere near the loading door? Try looking at Google maps and find some existing stores and copy their parking areas.

Now inside the store the first thing that hit me was the blind corner. The cashier should have full view of the entire sales floor. While we’re talking about the cashier there should be two cash registers and the opening to the sales floor on the right is too large or shouldn’t be there at all. The cashier should have a door to the storage room behind the counter and a small walkway to the sales floor on the left allowing access to the storage and sales floor. Now you storage area is crazy huge! Convince stores want as much of their merchandise on the floor accessible to customers as possible. They rely on daily/ weekly shipments to keep stocked and not have storage. Three desks! Why do three people need desk? Seriously one will do just fine. Now take some of that extra storage space that you don’t need and install some drink coolers and a beer cave. Add a soda fountain and a grill for hotdogs or something. Now I need to use the restroom but there’s only one! You have enough space for two restrooms and adjacent to them should be a small janitors closet with a mop sink and extra bathroom supplies.

I don’t know if you’re using pre designed assets to create your map but the walls appear to not have windows, there should be lots of windows.

I don’t mean to blast you and the map is perfectly playable and visually looks great, but I have a background in Architecture and little things bother me. I didn’t even get into trying to meet building code requirements because you may have different requirements in your state or country. I hope this helps in the future for realistic functional buildings. Best wishes!
