If you are coming directly from outside to a heated space, it’s likely the space near the door Is over-heated because of the loss to outside.

Hotels, big stores, event spaces, and other things with frequent entry/exit usually have a double door setup, meaning you walk through two doors and an air gap to enter, to minimize fluctuations in the main building. That space usually has heat going whether the door is open or not, so it gets rather toasty. Places that don’t have the buffer space will often have heat vents near the door cranked up to account for heat loses.
