Does anyone have any trade secrets for their line of work/employer that would shock and/or help the public if they knew? Any dirty little secrets you are willing to share? i think it would be helpful, there are so many loopholes in different areas of life, i like finding out tricks to making my life easier and my pockets fatter

i can start...banks clear checks largest to smallest. for some reason while i was a teller, none of my customers knew that. for example, if you have $100 in the bank, and you write a $75 check and 4 $20 checks, the $75 is coming out first. why? because you are going to bounce more checks once they take the larger check out first...in this case they get to charge you for 3 bounced checks, instead of taking the 4 $20 ones and bouncing the one for $75. that will cost you almost $100 in bounced check fees, as opposed to the 1 charge. its all about money!
