I'm a restaurant professional and have for a long time been wondering about the reason so many diners order their salads SOS (thats shorthand for sauce, or in this case dressing, on the side). Personally, it offends me that my customers don't trust me to properly dress their salad. But there's the rub- what is a 'properly' dressed salad? I think it comes down to; does the customer think I'm going to put too much or too little dressing on the salad? So please, you know who you are. Do you ask for dressing on the side because you want more or less dressing than you think you will get if you order the salad dressed?
