All of this nonsense is simply because consumers have been "taught" to behave this way. It all started when companies like K-Mart etc began offering unconditional money back - then we have PayPus saying "use us to pay or you will be ripped of by those nasty sellers".
Consumers expect far too much these days. It is fair to think that a new product will work as you intend but it is certainly unreasonable to think that a 15~25 year old, complex machine that probably has been operated in a commercial enviroment for many years will also behave flawlessly.
A few lamps out - - I would have told him to go jump at that point!!!
