<human>: Can you provide a brief rundown of the text in within 3 sentences?

So I work as a valet as stated in the title.

On this particular evening I happened to be working at a high scale resturant with a private function that made the parking lot look rather full while the resturant was empty. This resturant that had a rather large parking lot so those who didn't want or need valet did not have to valet with me (important for later).

So I was working and a car pulls up to the valet stand and puts the car into park so I go an open the door for the passenger and say hi how's it going. The passanger then asks do you know how long the wait is? 

Me- I don't think there is one but id happy to go check for you if you want. 
Her (rather rudely)- we don't need you anymore well go park ourselves.
Me- ok I'd be happy go check if you want though
Her- no we don't need you 

Her husband looked rather embarrassed that he just wasted my time asking for the wait and then having his wife rudely say she didn't need me anymore. 

Well as it happened their car battery happened to die while they were eating in the restaurant because they left their lights on... Hey they didn't need me so why would I inform them of this. 

 Well after their dinner they discovered this and she came up asking if I could give her a jump and I got the joyous occasion to say "miss I thought you didn't need me. I'm sorry but no I can't give you a jump I have customers I have to attend to".

Her husband laughingly gave me a twenty  to jump his car which I promptly did.
<bot>: don't be a dick to a valet and the. Ask for help. Jumped a ladies car who was a bitch for twenty bucks.
