Banker's cheques are completely unnecessary in Kenya! They are not any better than personal cheques... in fact, they could be worse! A bank manager once told me never to accept them; according to him there is more fraud involving bankers' cheques than personal ones.
Think about it: why is it that these cheques also go through the same clearing system as personal cheques? You still have to wait 4 working days before you can get the money.
The manager in question advised that people should simply accept either personal cheques or no cheques at all!
Nothing is real unless it can be named; nothing has value unless it can be sold; money is worthless unless you spend it.
