SNOW.. SNOW..SNOW..WHEE! SERIOUSLY...
Being retired gives me the option of choosing my shops. I go lightly in the winter and watch the weather reports before scheduling. I have performed shops over the past 8 years when most people would not venture out. The average motorist should not copy me.
I love driving in the snow. I respect ice and because I have been trained to drive in emergency situations both as a volunteer and in my past employments. I know how to go out when everyone else was coming in out of the snow and ice. My vehicles are stocked with blankets and first aid kit and other survival equipment. I can be safe up to two weeks if I am stranded and do not leave my vehicle.
A first responder appreciates the fact that most people stay home. It gives us plenty of room and less obstacles or hazards like SUV's that think they can go anywhere at any speed. They forget they also have to stop and turn. I stop when other people drive past these SUV's and offer aid when they crack up. I mention SUV's because they are involved in most of the winter incidents I stop at.
I will not gamble my vehicle to make a few dollars. Let me think. Do I want to wreck my vehicle for even a $100 bonus? I am not a moron. If it gets that bad the police will order everyone off the roads and the businesses will close. If the businesses are open and you show up and you are not a first responder or tow truck or plow driver they know you are the mystery shopper.
Your attempt to perform the shop will not give the client a fair evaluation. Stay home and ask the schedulers for a “mulligan” (do over). All they can do is cancel you as a shopper. That is better than the reality that unless you are a first responder you should not be out there. Do not risk your life.
Some MSC (like market force) tell shoppers that shopper's safety come first. All MSC's should have an understanding with their clients that human life is more important than the performance of a mystery shop and put that into their guidelines so the shoppers do not take foolish chances.
