(Not really) great news for the evening.

I have to do extra hours on saturday.

And I will be the only technician at work, other than that its only the customer being present.

Great. It could have been a great weekend and now it is just a pile of badly wasted time at the office. (cause either everything that will be tested is ok, or we will have to fix it on monday. I am not the guy with the customer knowledge but rather the technician..But that does not bother anyone ;) )
