They are confident, they are underestimating the virus.
They are underestimating the virus though but some people still going outside to do an errands that can't sustain their needs. No one is safe actually until the vaccine release globally. Once vaccine is out people can go to the casino but these days government allowed businesses to open. Must follow the precaution to be safe from this pandemic era.
We understand and know about it but for those people that doesn't have important things to do, they don't have to go out. But as for gamblers, we know it that they have to go out as we're not all the same that can allow ourselves stay in the cave for a long time.
Kudos to those scientists that are doing everything they can to create the vaccine.
