Errant SMS but in the same vein
Once had the pleasure of 80 box to desk jobs on a weekend allowing Finance to move into a shiny new floor.
Boss at the time was unavailable (probably a good thing, motorbike/ashtray etc) so I dutifully installed, asset tagged, imaged and tested the wee beasties.
Chuffed but a tad tired I retired to the hostelry of choice for my liquid reward(s.)
Boss decided to check in early evening and was surprised that the task was complete and I'd left.
SMS arrived thanking me for my efforts which I duly forwarded with a suitably sarcastic comment to a Colleague. Pop phone on bar, order a hop squash then had the "oh fsck" moment. Checked messages and yes, I had tapped reply not forward. Phone went into pint and I continued until last orders.
Following morning my praises were being sung to the newly desked colleagues bay said Boss with not a mention of the message.
Lucky that as I became a permee and had a mostly happy further decade there.
