This is something I've thought a bit about... how many people will inwardly recoil at the greeting hug of a friend they haven't seen for a while? I'm pretty sure I will. I'll be glad to see them of course, and glad to receive that hug, but I'm sure I'll also feel a bit more unclean or in danger for doing so.
On the other hand, this shakeup might have been good for us... going to a restaurant for dinner was once a special occasion event, and for many people have become an almost nightly ritual. We have a few friends that had never made a meal in their kitchen until the pandemic hit. Does the population or the environment really need to accommodate these excesses?
I'm still considering getting a "selfie-stick". Not because I take any selfies at all but they seem practical to guarantee others socially distance, especially if automatic telescopic models.
The hospitality sector is a mess. Gentrification and venture capital investments have totally changed the sector and destroyed a lot of the atmosphere. Not to mention the "special" activity it once was. The irony is that it's at the same time backed by ridiculous prices and staff is still underpaid and must "beg" for tips. Real estate needs to be fixed first, but the Middle East and China love investing in it.
