Barefaced technician

After buying a simple USB print server from LinkSys for one of our USB printers:

The Linksys printer server is also a switch and we do not allow switches on the network except professional switches such as the ones managed by ISU. If you want to plug anything into the network or want to buy anything computer related then you need to speak to us first and we will tell you a suitable product that we will allow. I'm sure you wouldn't be too impressed if we bought your lab equipment for you.

Damn cheeky monkeys, they seem to forget why they have a job. That last statement should be printed as a book and whacked across their heads, several times. Besides, 30 quid for the LinkSys device or a ludicrous £170 for the HP print server our lovely technicians suggest?
