On the one hand I understand how exhausting, annoying and embarrassing it is to be in a public place and hear people having a phonecall or video meeting that really ought to be private.
On the other hand, I have HAD the experience of “the only possible times you can make this extremely personal medical call are 1. On the bus to work or 2. During your break at work in a public cafe within walking distance of workplace” …and I can confidently say I was having a worse time than anyone overhearing the call.
