Sometimes, the SPs' excuses can be hilarious
a) damaged phone chasing her dog
b.) left phone at home
c) overslept
d) grandma in the hospital (thought she told me her grandma passed already)
e) hangover
f) sick
g) period
e) one with no excuse or explanation
I have had a cancellation within 15-min after confirmation. Said she felt wierd after taking some drugs.
99.99% of the time, last minute excuses are B.S. Most likely, it's overbooking on the part of SPs or found a bigger fish to fry.
