please help - how to find something at LGA

first and foremost: ik rules are against lost and found, but this is more so about the process of finding something, so i think it’s fine. if there’s a better laguardia subreddit for this kind of thing, plz direct me there.

i left my apple watch at terminal C of security like 3 hours ago. is there any LGA-specific hotline or something to get in touch with? the online portal is just some third-party service that i have zero confidence in. please help, thanks
