the money mess relationship

i couldn't think of a catchier name. sorry. but here's what happened:

i went to halfords to buy some wind screen wipers for my car. i returned home to fit them myself, didn't really know what i was doing but how hard can it be? well, as i was clipping on the first wiper it broke. i may have been doing it completely wrong but it was hard to tell.
so i took out the second wiper, and managed to attach it fine, if a bit slowly. i went back to halfords hoping for an exchange since the clip in the middle was broken. here's what it went mental.
lady at the cash register, who we'll call "mental of the day" or menday for short, told me to get another member of staff. i found one, lets call her jonny, who just went and asked someone else, who we'll call cool dude who i think knew everything about every car currently in existence and how to fix anything using all that they sell in the shop. or dude for short.
so jonny lady, after directing me to dude, who was busy, comes back with an entire replacement part. cool. menday, then wants to put it through the till, i assume for stock or something. she tells me off, saying they're only gonna do it once. i said, it's not my fault it was broken, and if this new one is broken i think you have to replace it too. she didn't reply because jonnylady then tells her to not put it through the till. that comment then set off mendal who went apeshit with jonny.
a one minute argument in front of me was followed by a one minute argument in an aisle far away but in my line of sight. she then comes back, takes my card, and then just runs off somewhere else in store. with my card. how very odd.
over 5 minutes later she comes back, and gives me my card back. i don't think she did anything on the till with it.
she also gives me a replacement clip. i say i don't need it, i already have a replacement blade. she doesn't get this after 5 times of me telling her and showing her that the blade i have is now fine so i just leave with my new blade and replacement clip.

this story has a happy ending* as i carefully remove the existing blade to see how to fit the second new one, which passes by without incident.

the end

as i went home with my extra clip, i realised that i would save it somewhere should i ever need it.

I will NEVER EVER need it.

i know however, that i will save it. and i realised i could probably throw away loads of stuff i 'might' need which is taking up lots of space. on the off chance i need something i've thrown away i could probably buy it off ebay for less than £20.
and that's when i realised there is an interesting relationship between hoarding things and money. hoarding things saves money, but is it worth it?


also, does anyone know what the point of collar straighteners are? (ie can i throw them and the spare ones away!?)


*i'm assuming she won't try to commit any fraud with my card having spent 5 minutes in the back of the shop cloning it.
