Nice that someone is even thinking about this kind of thing. 4th qtr unload and flow have been pretty rough with this modernization crap.
Food is always good; working flow means working up an appetite.
All the "I appreciate you" lines get old. For one thing, "talk is cheap." But hearing the same line doesn't really mean anything after a while. Tell me that you appreciate that I got a huge amount of push done in my area, or that you overheard me providing great guest service, or you have an extra hour or so to give me so I can get caught up on back stocking.
What would be super-duper world-shatteringly awesome would be to tell me that you've talked to the DC about how they pack and label the repack boxes AND they've agreed to do a better job at it. That would be a huge morale booster. But that's only a dream, so we're back to food. And the flow team at my store always likes food.
