No. I worked at an airline where the company typically charged itself higher than retail for tickets. At least, it was the highest fare type.

I worked at a media company - we had to pay top rates in order to buy our own ads for cross selling products.

Finally, I work at a SaaS company who heavily uses our own product. While we don't pay for it - just our cloud hosting bill - it's definitely a discussion point about how we should be a bit more mindful about usage.
