My local version of this involves four different establishments adjacent to Bass Pro Shops. Raising Cane's, Chick-Fil-A, Starbucks, and McDonalds have at one point or another, caused backups on to west-bound Sunshine Street, a major east-west arterial for the city. Below is a diagram of the signed overflow route, used to prevent Sunshine from backing up by allowing customers to enter through the back side of Chick-Fil-A, McDonalds, or Starbucks.
I'll snap a picture of the signs soon-ish, driving during tomorrow/Thursday's icy weather doesn't sound appealing.
Cane's lines still occasionally wrap around the building, but during the first 3 weeks of business (circa Nov. 2020), the police had to assist in directing the heavy traffic, which regularly backed up on to Sunshine. The Cane's line setup is also potentially dangerous. Here is a diagram of the convoluted setup:
People in this town really like to clog their arteries, then proceed to, you guessed it, clog their arteries...
