Yes I do have a text, but some want to phone and tell me they are on some random road they don't know the name of, where am I? do I mean this road, that road. They've put the post code into the sat nav and realise they are an additional 30 minutes away. They don't have a map, don't have a sat nav.......
Does this happen to you a lot? Are you in an odd location?
It did when I took short notice bookings, guys who book 1-2 hours in advance don't have the problem.
The main issue was that some people didn't realise how far they were from my town, or would phone when in the town not knowing which road they were on. The town has several main roads running into it and I am right next to 'the' main road in the centre.
If someone tells me which direction they are coming in from I send clear directions from that road, but if someone is already in town and can't tell me, and don't have a map or navigation system then it's hopeless.
For the distance from the town itself they'd tell me they could get there in a certain amount of time, but they actually didn't know the distance or would be being over ambitious. If they told me where they were I would give an accurate time for them, but that's the trouble some men didn't want to tell me where they were driving from.
I found that those who book at least 1-2 hours in advance seemed to be able to be more organised, would pop the post code in and follow my directions no problem at all.
