I agreed for 3 (t r and!) the day before the haircut - hop hop, brother, recorded, come, we are waiting. I come at the appointed time - again a complete misunderstanding on their faces, again oooooh, braaaat, hop, he felt bad, left :((((((
To call to warn - no, it's unnecessary. Allowing a person to leave work earlier in order to get a haircut - yes, it's not our problem, hop-hop.
You don't need money and customers - don't work and don't take orders. It's so disrespectful to waste someone else's time, forgetting about any professionalism or at least a hint of work ethic, you still have to try to do it right.
Disgusting. Avoid it by all means if you respect your time, because in this tavern it will definitely not be respected.
