Great job OP, I'm glad you were so considerate and hope all goes well with your angel of a husband!
NancyLee61... I live in Sunny South Africa and even in the winter we have a max of -2/5 degrees Celsius. So I cannot begin to imagine extreme weather conditions. But even I can clearly see that such extreme cold does not mean "hey just put on a jacket and boots and you'll be fine"! I assume it affects the safety of the roads, the hazard of frostbite, visibility issues. I'm sorry but I would NOT just bundle up my kids and take them out in that weather. If schools are closed, that means its not safe for them to be travelling to school. Risk my kids health for a cake order? Never.
I just find it quite strange that you feel the need to compare saving a life to delivering a cake? Seriously?
I run a successful corporate business (not in cake) and we push to deliver our orders on time at all time. But if it meant putting a driver's life at risk - a driver who has a family back home who expects him to arrive at the end of the day safely - no, the customer needs to wait. And we inform them asap, we make arrangements for soonest delivery or alternative solutions and offer the best service we can.
Business is business. Life is life. I choose the latter when it comes to my family and I'm sure the OP does too.
