2002 Honda Odyssey Spark plug replacement

Hi,
I recently had the 90K service done on my 2002 honda odyssey. It incl spark plug replacement. When I got back my car, I was chrged a extra hour of labor for spark plu replacement. When questioned, I was told that this is because the coil packs were individually wrapped around each spark plug and that they had to be removed before changing the plugs.

My question to you is. Is this a typical arrangment in all odyssey Vans of 2002 with V6 engine? I want to understand whether this should have been covered in the standard work time or is it really diff in my van for which I had to be charged more than the normal service package rate quoted.

Thanks,

Kiran
