when I get the chance to visit supplier sites, and there aren't many of them, IDK if it's because my company is shit or I'm too low on the totem pole, but nobody picks me up, nobody pays for my hotel, etc. I'm expected to find my way by myself. My employer gives me a list of hotels they have a discount with which is what they'll reimburse me for, and I get a reimbursement for Lyft.
On site I get a brief, highly scripted tour that I know showed me little of importance. Then I get a lunch, maybe a dinner at a restaurant. I still go whenever I have the chance because it gets me out of real work for 1-2 days but it's fucking wild to me that people take 15 day business trips with a free vacation thrown in. And I don't think it's because my employer doesn't place big enough orders either.
This is it in a nutshell really.
There's a difference if you're a simply a process audit guy and if you're the owner/C-suite/Buyer in charge of pulling the trigger on contracts with lots of zeros.
There's a difference if your business with them is 0.1% of their turnover or 10% of their turnover. Even then, there's a difference if your business is in a strategic market for them or not.
The difference shows in whether they meet & greet you, whether they take care of your F&B, how they wine and dine you, who you eventually get to sit and meet with, etc. Even in a trade show, it's the difference between whether you get a table in the main area or a private meeting room away from all the distractions on the floor.
This difference pretty much transcends all markets and cultures.
Oh, btw, the guys on the sales side that takes care customer accounts? They very typically do 10-15 day trips to meet with their customers. Not just one customer of course but a string of them within a logical geographic region. Not uncommon for them to shoehorn their own personal itinerary into the overall trip. A trip to the tailor here, a bit of shopping there, some sightseeing in between ... I have a couple of them who always show up when the F1 GP is in town.
That's a whole different kind of "corruption" going on that side as well.
