Profile
"A silver-tongued salesman, where there is profit to be made, you can be sure Sampo is nearby.
Sampo’s unique knowledge makes it hard not to approach him for help, but becoming his “customer” is not necessarily a good thing.
After all, “customers” can quickly turn into “commodities” for the right price."
