If you ever hire a rugby team to do some work. Wait with the beer until after the job is done!
Pain in the ass/fingers
Every product had TEN rubber strings from the moulds casting beard. They had to be individually cut off by hand. Multiply that with a few thousand and you got a real pain in the ass (The pain was actually located in our sore fingertips.).
To motivate the guys I offered home made chilli and beer. Instantly I realised it was a bad idea opening the first case of beer so soon. They quickly became loud and started having fun showing off their strength by pulling my precious inventions to shreds. The rumour of free beer spread and more people came to the club to drink, wrestle and demolish my stuff.
Hungover packaging service
When everyone had sobered up a few days later, we restarted the job and eventually I had my first order ready for delivery.
