So I started going to a nice hairdressers back in January 2024. Really like the place and the staff and I don't need my hair cutting that often, perhaps every 2-3 months. Its now July 2025 and I've worked out that during that time, my appointment has been moved on 5 out of 7 occasions. Sometimes to an hour or 2 later but more often to a different day or week. Is this fairly typical or should I start looking for a more reliable hairdresser?
