I lose more device screws than anyone on the planet. I excel at this in both speed and quantity. I drop them down heating registers, into my clothes, into piles of sawdust, crawlspaces. I haven't swallowed one yet, but it's a matter of time. Sometimes I just put them down and 1 second later they're gone.
I'm adding a new Murphy's law for this. The more unique the fastener, the more likely it will get lost.
