Hey so I've been doing the dooble or triple-booking technique for the weekends since is the time most girls are available to meet. I usually go with the I'm sick approach but that kinda shoots myself in the foot because sometimes I want to meet them the next day when I'm supposedly sick (and they might be worried about transmission and such).

What excuses to flake on girls are credible and won't piss off the girls so we can meet later?
