If you had to pay $200 for pizza for 12, then to buy pizza for 5,000 the cost is 200/12 x 5000.
You won’t get a bulk discount because you won’t be buying it for the entire company at the same time. Different teams have different team building events/times.
The point is to have a party for a team of 12, they were spending $200. It does not matter whether it was all eaten, they spent that amount for the team.
We can thus assume that if all teams did something similar (why would you only allow some teams and not others), the dollars add up and that is how you look at it from a company perspective. Not the one team’s spend, but the overall spend.
