Nate--thought i did answer you on fb, but i was rather travel frazzled, so maybe i thought i answered and it didn't actually get typed. aaaaaaaaaaaaanyway....
talked to the manager, he pulled the receipts, looked at the transaction on my phone (since i'd accidentally left my printout from my bank thing at home--oops) to see that it was, indeed, not the same amt as on the printed receipt that i signed. chalked it up to the server being tired and mine being the last receipt he entered that night and that he fat-fingered the key. gave me back the difference. my problem was not the money itself, it was the error. more to the point--when you're dealing with people's money, you've gotta be more careful. mine was in the "ones" column...fat-finger the wrong number in the tens or hundreds... really...just pay more attention and do it right. 5 more seconds. see that the numbers match before you send the charge through and batch out... i ALWAYS double check my numbers when running charges or tallying totals for my customers...
but anyway. it's been long enough, i'd kinda forgotten all about it til this thread popped back up. rather surprised that it did. but now ya now, and knowing is half the battle.
go JOE!
(i dunno..i'm still sleepy...carry on...)
