I only give elbow bumps when I'm working on the line (I work at a Quik-serv restaurant) and want to give a high-five but can't because I'm wearing gloves and the other party isn't (or vice-versa).

That being said (and somewhat unrelated to the topic), the chain I work at has started to move away from our previous interpersonal-style setups to a more closed-off, grab-and-go-type model. I don't really recall if it was influenced by corona or if it just accelerated the change at all, but I will really dislike the loss of being able to personally serve a customer their food for dine-ins, or personally going up and asking how they're doing right at the table instead of having them come to get it themselves or needing to inquire from what feels like across the room due to social distancing. I think some stores in the future may not even have dine-in space at all, or very few, and it saddens me.
