So many people get a boost from the ice cream. Its a nice little break from the grind, and the company pays for it out of pocket. The owner of the company even comes and gets some ice cream.
One of the analyzer instrument manufacturers buys our department a pizza party 2-3 times per year, and a standards company we use sends us a pre-paid Visa for our department to go out to eat once a year. Every now and again a client will send money to have a restaurant cater to us either for doing a great job, or if they are closing out a contract that we did well on. (For those Ohio people, we tested for the big Fernald decommissioning - at the close of the contract, they had Moe's Southwest Grill cater).
Our Christmas party is usually an oyster roast in the company parking lot, and they rent a beer truck
Free beer is the best beer!! Last year Rob and I really enjoyed ourselves - it was the first time either of us had gone to one (he'd worked here 5 years and quit in 07, I've been here 3 years in August). They had desserts, oysters, BBQ pork and chicken, snacks, and the beer truck with a bonfire. It's pretty nice, and the company buys all the food.
