Out and about sketchcrawling with a buddy from the old gaming days. We went into this little place on a whim - could hear the music from the open balcony. Sat right up front to sketch the band, which ended up meaning we sat at their table. So we showed them their sketches and hung out.
The ladies at the bar were less cool with being sketched. Got the cold shoulder when they saw it. I guess in this setting, 'acting sketchy' gets you classed with other stalkers. Or maybe it's just not a flattering drawing. Oh well, can't win them all.
