I teach sewing in high school, I've had kids, teachers, district office personnel, the principal, the security people - all ask us to mend things for them. Oh, and let's not forget the parents - they send stuff with their kid to school and ask if we'll mend it. And the principal even asked one of the boys in my class to make him an apron - the principal is 6'7", so am I supposed to alter an existing pattern for him and what about the material??
We say no and in the case of the principal, we never mentioned it again and neither did he.
