Yes, there is! Although carrying round your own special mug is just as suspicious really, unless you carry round a cup of coffee and finish it off at the table. Or ask the waiter to serve someone's coffee in it, either way you've got to deal with the dregs soaking into whatever form of ball you're using.
I think as with so many things it depends strongly on the effect, and the persentation. If you use a prop, and make it obvious it's a prop, and do something that could only be achieved if the prop was gaffed, then you're asking for trouble.
In terms of the chop cup - I think it's perfectly reasonable to expect that if a magician wants to show people a cup and ball trick, he'd have his own aesthetically pleasing cup to use... just like if you do a lot of writing, you probably have a nice posh pen. All you have to do is let the spectators examine the cup and the ball briefly at the beginning, and away you go... by the time the second piece of fruit has appeared, the last thing they're thinking about is whether there's anything special about the cup - having a cup gaffed as the chop cup is doesn't do anything to help you materialise a lemon!
