Redrill and retap some holes while they wait, and charge $20 for it, then they piss and moan "where are the screws ??". You mean the ones I had to drill and tap out because you monkey-fist fuked them up ? Screws are $20 for 4 (we custom make torx t15 head screws from 4140 and heat treat them, then black oxide them, so $5 a screw.. do the math). That's ontop of the original $20.
Then it's like 15 attempted minutes of useless negotiation, which results in me saying "job is $20, screws are an additional $20, no discounts".
If you are polite, stroke my ego a bit, and say please and thanks and call me a nice cunt, then yeah, I'll do it for $30 cash.
I need to get out of this industry.
