Are you sure you didn't just see a sales meeting?
If you're a farmer in the market for a $200k combine harvester, sales guys will be happy to put you in a $200-a-night hotel so you can attend their invite-only presentation on how their latest models give you 10% more yield with 30% lower labour cost thanks to the new auto-steer mechanism and six-stage threshing mechanism. And they'll hand-hold you through all the calculations to write a business case.
Considering how much the sales division of many medium and large companies dictates the direction of the whole company, "sales meeting" and "business collusion" is often the same thing.
I've worked for FAR too many companies that have lost $60million in support and maintenance on a sub-par product that sales managed to sell for $30million gross... and then the sales division (and upper management) leave the company for something better. What a surprise.
You can rest assured that bribery in that way is extremely common in the West.
used to be a sales engineer at an ISP. one you've heard of. we had account execs straight up offer "referral agent fees" to the network managers we were selling to.
bandwith is mostly the same -- 10Gbps here is more or less 10Gbps elsewhere -- so you gotta set yourself apart. and it worked. constantly.
