The phone aimed itself at the wall of inventory. The app zapped. ZAPPO! Success! There's the product. Uuuuh! Uuuuh! The product isn't jumping down to stock itself, where the customers can get it. --- Problem 1: There aren't enough employees. But to get enough employees, they have to raise pay. Here comes Walmart-ain't-so-cheap any longer.

They might be faithful to company and doing-a-good-job, but they are beyond the breaking point for stress. --- Employee hidden benefit: Any employee who can take the stress mentally, will find his IQ increased. That's what stress does - like a cornered rat frantically looking for a way out.
