1- You realize at 9:10 that your 11 am meeting is actually at 9:30! You made a mistake with the timings and the client is a SUPER-important client who gives you dagger-looks when you walk in 20 mins late and find you were holding up 10 other people.
2- The laptop that had the presentation you had to give CRASHES (at above-mentioned client’s meeting). Yeah. :-\
Some days it just doesn’t pay to get out of bed.
I feel it necessary to mention that I managed to salvage the meeting anyway. We had a backup laptop so the presentation was done. I can be quite persuasive and charming, when I need to be, and by the end of the meeting, they were quite happy with us. :)
