Your fever dreams aside, could you cite a single example of someone, somewhere smoking in a line in a bank or store?
I'll concede an amusement park, in the interest of fairness.
Until ordinances were passed prohibiting it about 15 to 20 years ago (at least in my hometown in the DFW metroplex) it was common for people to smoke in line in banks, grocery stores, the ticket line for the cinema in the mall, etc. I am particularly aware of the banks, because at the time I worked in one.
