Many times I'd look in my bag to find someone else's clothing. One time I ended up with a young ladies lacy underwear which kinda made me feel like a creep.
During my move from SF to Ann Arbor I made the mistake of outsourcing the washing of pretty much all of my clothing and linens with them. They lost all of it and couldn't find it for about a month.
Let's just say I am very glad I have a washer and a dryer in my home. Certain things just shouldn't be outsourced.
