To ask would you expect to pay more if you called a workman out on a Sunday?
DH is in the infancy of a new business and is looking at having a 7 day a week call out but says people charge double for carrying out work on a Sunday.
I think when you are just starting out you should charge a flat rate, build up a reputation for being reasonable and reliable etc.
He says not, I say shops etc are now open 7 days a week as standard and Sunday is no longer a big deal.
Settle an argument!
