Sleepie, I'm so sorry about your monetary loss
. Proud of you for being sober tho! I've been an employer for years--there is nothing wrong with using a calculator or a scratch pad! Everyone has their strong points and their weaknesses at work, I always have told my people-- whatever it takes to get the job done well, let's do that! Calculator is fine. I wish your boss would've made up the 30 tho, stuff happens.
