Why are guests obsessed with feeding the baby??

I feel like partially I'm just being anal-protective; but does anyone else have guests that always insist on feeding your newborn? I don't mind them holding him, hell a friends wife held him for 3 hours the other night, but when it came time to eat she begged to do it (then she failed to notice it was tilted too far down and who knows how long he just gulped air). She's the 4th or 5th person to do it. I get me and SO's mom's but I'm really finicky about people feeding him. I'm a FTM so maybe just need a chill pill?
