Once I reported that my bank’s ATM was spitting our $50 bills instead of the $20 bills it should have. It took awhile for someone to take me seriously as I explained the problem. The young clerk was amazed I had reported it and insisted on returning the $310 too much it had given me (yes, I confirmed the withdrawal figure was counting $20s and shoving out $50s).. In response, I quoted some couplets I learned a long time ago: “I have to live with myself and so, I want to be fit for myself to know. I want to be able, as days go by, always to look myself straight in the eye. I don’t want to stand with the setting sun and hate myself for the things I’ve done.” It’s part of a poem I memorized decades ago and had stood me in good stead all that time.
The math doesn't work. How could you get $310 too much by getting $50s instead of $20s?
If you took out $200 expecting 10 $20s and got $50s instead, it would have been $500 - or a $300 difference.
If you took out $220 expecting 11 $20s, and got $50s instead, it would have been $550 - or a $330 difference.
