Smart organisations and managers remember that rewards are not always monetary. They can be as simple as a pat on the back. My wife once had a manager who used to bring her tea and muffins when all hell was breaking loose. She worked harder for him than she would have had he merely given her a raise, or worse, ignored her work. By getting to know her well enough to realise that she liked tea and muffins, and to recognise when she was in need of encouragement, he demonstrated to her that he appreciated her as a person, not merely as a unit of production.
Monetary rewards are nice, and they pay the bills, but they are impersonal.
If you can't say thank you in person, it looses a lot of the impact. Chickens do not have lips . Vendors often tell you that your problems will be solved if you just buy their whizz-bang technology.

If a vendor analyses your operations and recommends that you buy their technology, you can bet that they will tell that this technology will solve your problems.
