"It's not really your fault the detergent left enough cooking oil to oxidize and self ignite."
Cannot speak to modern times, but for ages laundry/housekeeping manuals gave specific warnings about things contaminated by flammable substances. Specifically such things were *not* to be machine dried unless or until one was absolutely sure all traces of oil, grease, fat, or whatever had been removed. This was on top of the warnings about using "home dry cleaning" solvents or spot removers then putting such treated items into a dryer.
It wasn't that long ago that housewives were using gasoline or kerosene to "dry clean" items at home. Then of course you had shop rags, rags your husband used when working on the car or some such, if your husband's job involved being in contact with petrol substances and so forth.
Restaurants are a particular worry because staff often use napkins or towels to clean up oil/fat spills. If those items are not disposed of/stored properly prior to laundering and or that process is not carried out properly you can have problems. http://www.semissourian.com/story/1778136.html
Many operating Laundromat or whatever business think doing restaurant/kitchen linen is nothing special. However it is a well known fact employees of such places often grab whatever is at hand (napkin or towel) to clean up any sort of spill. If these things are sent to the laundry and the operators do not know/understand what they are getting, again you can have problems.
