Not too bothered about scratches as long as the gear still functions perfectly. I'm pretty careful with my gear with knobs and not knocking it around and making sure it's all set up correctly.
I hate when other people handle my equipment though, they never treat it right. Even my housemate who's also a sound engineer is always putting boxes on top of my mics, cables and loose rack gear. Bugs me to no end, there's a load of scratches in my stuff that I didn't do.
Some people are very rough with gear. I've a few mates that are always breaking stuff and blaming it on bad luck. Bull shit, they're too rough with their gear and it breaks. Simple as!
