Can I risk just pointing out a few things on behalf of tradespeople? We have a small family business part of which includes doing repairs in people's homes, we explain that there is no call out charge but there is a minimum repair charge, we always confirm the price before going ahead and pride ourselves on our service and integrity. However this is a business and we have costs such as purchasing and maintaining a vehicle, advertising (you have no idea what Google charge) public liability insurance, administration, taxes - and that's before we pay ourselves or small staff.
I accept that there are rip off merchants out there, but I don't think they're in the majority at all and maybe we all need to consider the above when thinking costs are a bit steep.
Ducks!!
