I'm going to back up just a bit to write about our first night's stopover. We spent it in Iowa at the Lakeside Casino, fka Terrible's, and although I'd love to have seen about visiting @IowaDee this was obviously not the time to do so. Last spring everything was closed down, and the parking lot was empty. This fall the Casino and hotel were back up, I don't know to what capacity. We weren't interested in going in; we just needed a place to stay where we could easily fuel up the next morning.
I've written that we had plenty of road food, but we do very much like Subway sandwiches. While my darling refueled the pickup, I went into the Subway for our preferred BLT sandwiches. The door noted that masks were required. I had mine on. The customers had theirs on. Neither of the counter clerks did. I wondered whether to speak up or leave, and opted (wimpishly) not to do either. When I paid, I asked the clerk why they weren't wearing masks. She gave me a song and dance about not being able to wear one due to a nervous condition. I bit my tongue and didn't say something like "I hope you don't plan to be a doctor" or give her a sermon. I just paid, got out, and filed a complaint with Subway on their "how did we do?" survey on the receipt.
I haven't heard anything back from Subway. At our next fueling stop, this time in Kansas, I had to go inside to pay with a credit card. In that building, none of the Subway staff was wearing a mask. Is this standard for the chain? I've decided that next time(s) I go in, if they aren't wearing masks I'll either leave quietly or, more likely, say something and then leave. We have plenty of sandwich fixings anyway.
