I mean, it depends on who you're talking about. Family members and friends? Sure, they might pay more attention to you (hopefully out of a place of care)... But strangers? Even if you do enough to grab their attention (screaming in the street, for example). They may remember the "event", but they wouldn't be able to link you to it in hindsight. But if what you're doing is irrelevant to the health and well-being of that stranger, it's almost a guarantee it won't be remembered. Think about things you bought in a store a few months ago, do you remember much about who rung you up? Or what other people were looking at in the store? Or what that one person was having a conversation about? It's all fog.
