From  The_H1R0, Tales From Retail:

I work in a photo lab for a big box store that has both hour and self service. For the past week our machines have been on the fritz (as technology tends to do) and because of this we are unable to do certain jobs we normally do. Not a problem though, all I had to do was make some large bright yellow signs and affix them to every machine at the front.

The signs read "ATTENTION CUSTOMERS. DUE TO TECHNICAL DIFFICULTY WE ARE UNABLE TO OFFER "X", "Y" AND "Z" SERVICES. WE APOLOGIZE FOR THE INCONVENIENCE". Now in addition to each of these signs being at least 8"x10", they are posted right beneath the screen where anyone who ever hoped to make a single photo must look.

So that should be easy right?

I have since started a check sheet after the first two days and my results are as follows;

126 counts of "Are the machines broken?",

87 counts of "Can I not make (x,y or z. Take your pick.)?",

54 counts of "Can I not do (completely unrelated task) here? ",

13 counts of "If I can't do them can you just do them for me.",

and last but not least one very aggressive middle aged mother who decided it was inconvenient and I the clerk should just fix the machines if they are broken.

Not sure why I didn't think of that first! If this trend gets worse I think warning labels may lose all effectiveness, and I can decide if that will be a good or bad thing.
