No, BF is engaging is what is commonly known as pickle juice abuse. He needs to reported to the appropriate vlasic authorities.
As for my other uses, there are many, but the most common are:
1. I can be used in a marinade to add a bit of flavor or to add some zing
2. I can be added in small amounts to potato salad to create a different type of flavor
3. On occasions, i have been known to be included in a bloody mary. The bit of flavor from adding a small amount of me really goes a long way to giving the bloody mary a fresh new taste
i hope this helps you in your future cooking endeavours
