I was doing a video shop 1.5hrs away and followed the directions to a tee. Called the number to make the appointment with the targeted person. After a brief and somewhat heated discussion with the operator to speak directly to the target, I got the appointment. Finally they gave me the direct line & I called the target to verify the appointment, changed the appointment to an earlier time & went on my merry way. I arrive, do the shop, get the business card & realize that although I was talking to "John" it was not the right "John". I got in touch with my scheduler immediately hoping the shop was not invalidated totally.
I received a 50% penalty ($40) for the mistake & not given the opportunity to fix it.
Two other times I lost complete pay for cell phone shops because I did not pose an objection. Those were each half an hour away & took way too long just waiting for assistance.
It happens and it's all part of the game. I feel that the honesty helps the msc know you're not trying to bs them, but you simply screwed up. Forgetting to inspect the bathroom is not one you can bluff your way through tho.
Don't fret, just move on making sure to visit all bathrooms even if you don't have to, just in case. Lol! ☺
Good luck in the future.
