I’ve never personally been bothered by the ask-to-ask, the reality is I have a 100 WPM typing speed and “Sure, Whaddya got” is muscle memory at this point in life. Pleasantries and social oddities are just part of being a human after all.
What bothers me is the folks that ask-to-ask then go ghost for 15 minutes or more. You’ve captured my attention, please capitalize on it! If you’ve broken my concentration and walked away, _that_ is rude.
