AITA For not getting dressed immediately after I wake up and shoveling snow

We have the day off from work and it snowed overnight, my wife got up two hours before me and is outside shoveling the 5 inches of snow we got last night. She’s pissed off at me because I won’t immediately get dressed and run out there and shovel with her, claiming I’m leaving it all for her to do. My wife wants everything to be on her schedule, she wants to shovel now so I need to get dressed and shovel with her when she wants to do it. We don’t have to go anywhere, we have no work. Am I the asshole for wanting to have a cup of coffee first before going out to shovel?

Update for extra info: I got up at 8:15 AM, by 9:15 AM I was starting up the snowblower. By 10 AM it was done, all of it, driveway, walks and garbage area. I also cleared a big spot in the yard for the dogs, I usually do this. The thing is, and she knows this, she didn’t even have to get out of her pajamas I would have done it all by myself. The amount of work she put in was unnecessary, the snowblower makes the job nice and easy and she is afraid to use it so that’s why she didn’t use it. Bottom line, it’s 19° out, no school, no mail delivery, no trash pick up and we are not awaiting any deliveries from Amazon, FedEx or UPS. We have a running joke around here about how the Prince gets treated better than the king, I’m gonna have a talk with her later about making my grandson contribute more when it comes to things like this, wish me luck because it’s not gonna go well I think.
