Temporary stocking position, log it as exercise?

I work in retail, but this is no means a daily activity. Hours have been slow and I work 8-10 hours a week at most. This week I have been scheduled as a stock person. Lots of unloading, unpacking, lots and lots of walking. Normally I feel fine with my calorie intake, but this week doing the harder stock work, I am completely ravenous. Do I log it as exercise and if so, what? Retail is my normal job, but stocking is a rare occurrence this week.
