That's probably one of the WORST things you can say to a client that's having problems.

In their mind, it's all YOUR fault anyway. You selected the product, you sold it to them, you installed it, you told them it was great. Now it doesn't work - and how dare you compare your inconvenience to theirs. They don't care who made it, or why it broke, or how bad your day is - they just want it fixed, yesterday :-)
