Is it taboo to park in the first truck spot at a rest area?

When I go into rest areas after midnight, frequently there will be multiple trucks parked on the shoulder of the ramp into the rest area and on the shoulder of the ramp to exit the rest area. And, usually, all the semi-truck parking spots in the rest area will be taken except for the first parking spot in the rest area. This parking spot that I call the first truck parking spot in the rest area is the parking spot in a rest area that is closest to the entrance ramp to a rest area. It is the spot right next to the curb. It is the first truck parking spot a trucker will encounter when entering a rest area. When I enter a rest area after midnight and the first parking spot is available in a rest area, I always park in the first truck parking spot in the rest area. Intuitively, you would think that the first truck parking spot in a rest area would be the first truck parking spot taken in the rest area. But, counterintuitively, the first semi-truck parking spot in a rest area is usually the last spot to be taken. This has allowed me to get a parking spot in a rest area after midnight countless times. So I love this. Don't get me wrong. I am not complaining. But I am very curious. Why don't other truckers want to park in the first truck parking spot in rest areas? Is there some sort of taboo or unwritten rule against parking in the first truck parking spot in a rest area?

 

No. The first parking spot is not part of the roadway. There is no need to paint a line on the left side because the curb marks the end of the spot. Also, the first parking spot is the same width as the other parking spots, signifying it is a parking spot.

 

No because most trucks at midnight are parked for a ten hr break.

Also, this same phenomenon exists in the daytime too.
