I used to be a self employed Dental Technician George,never liked working Sundays,but in the Dental trade you just had to at times because of the amount of work coming in there was no way of avoiding it,and no double time either as it was all peacework ,priced per item made as woodturning is.If I was a professional woodturner I think I would have to state in my adverts/website that I didn`t/wouldn`t work sundays,just so people knew exactly where they stood before they tried booking,as it would save any embarrassing moments like you have just been through with this lady,Regards,
Eric.
