Can I get more of the white sauce?

One of the most annoying things about my restaurant is the fact that they are extremely stingy when it comes to giving out certain sauces. For wings, they give a tiny ramekin of blue cheese, and for one of our salad's, they kind of pour the dressing into the bottom of the bowl and plop the salad on top of it. Dropping off either of these two things always follows with a "can I get some more of the white sauce?" It's not such a bad thing at all though, I must admit, I love extra sauce on certain things. We're all human here, or else I wouldn't be arguing that servers are human too, but most of the time I will ask for an extra sauce if I have run out of the first, or was on the verge of running out. These people ask for it as soon as you get there, which is also fine, if they are going to use it. Hey, they could even be saving you the trouble from getting it later, but nothing is more disheartening than when you get a really low tip on a table that ran you around for sauces, sour cream, extra sodas, and useless things that they never ended up even touching! You better believe that these people will lick every ounce of sour cream out of a ramekin when you let them know that they were charged for it, but they will continue to ask for excess of any free sauce just because they can, not because they really need it.
