Having been deposed once the other lawyer spent 12 minutes asking me questions around a thing. The crux of the matter was if I had been verbally informed of what a line item was or if it was illegal to charge for said line item. This line item was unmarked on my receipt but marked on a different customers receipt as an illegal item to charge for.

Lawyer tried constantly to get me to answer a question that would set them up. At the end they gave up and asked "did they tell you this item was for X and they were not allowed to charge for that". "No.". The deposition ended there.

Given it was not a huge deal litigation and the deposition took place in my lawyer's dining room it was actually an interesting experience and not really uncomfortable. It was akin to doing a programming interview. Actually a lot less was on the line.
