I was going to suggest to anyone interested in VMS to head over to the deathrow cluster but unfortunately it's now dead. https://deathrow.vistech.net/410.html
I had a similar experience working for a food distribution wholesaler in Melbourne. We rode pallet trucks and time pressure was so intense that there were guidelines on the number of steps where it was more efficient to walk next to the pallet truck rather than ride on it. I couldn't keep up and lasted all but 2 weeks. This was 25 years ago and it's disappointing nothing has changed.
