It makes sense what you said, of course for people who run a business there are difficult situations such as shops that become quiet, but on the other hand there are also people who do not give up easily so they look for ways to keep visitors or attract new visitors in ways that they do such as one of them with what you said.
Apart from that, the question for me personally is, do these online casinos that operate have physical casinos? I don't think so, but with them originally running a physical casino and seeing the current situation they should be able to compensate by creating an online version of the casino.
In my town, it's not a sportsbook, but it is a horse racing place, where you go and bet on horse races and in that shop, there are always a bunch of people. Now, why would people go to a shop to bet on horse races when you can just sit at home and relax and bet from your phone or your pc? Because that dude made it into a "horse racing cafe".
This is not something we have seen that often before, I am sure it existed back in the day, or in other places, but not in my town. So people who love horse races, get together there, drink tea and coffee and whatever they want, on hot days maybe an ice lemonade or something. They watch the races on big screens together, chat together, bet together. Basically he created a place for those fans to get together and have fun.
