Sad story

be me
chilling at the crib by the lake
out of nowhere this couple comes out of nowhere and decides to spend the day at the lake
I wouldn't have a problem with this normally, but I was expecting to have guests later that day, so I get up and head towards them to ask them to leave
they begin to scream, I'm of a fairly large build, and I know that I can appear threatening when people dont know my personality.
They scream out "What do you want from us?"
At this point I'll do anything to help them settle down, I still need the space that they are occupying, but I don't feel comfortable rudely kicking them out at this point. Maybe I can just ask them for some money for the inconvenience, that's fair right?
As they are still cowering, I lean over and I tell them "I just need about $3.50"
Their fear turns into anger, and they just tell me to fuck off, as if I am the one who started the problem.
Verbatim they tell me "Goddamn it Lochness monster, I ain't giving you no $3.50"
Im still upset.
