salad dressing

i have a HUGE pet peeve. i'm so sick of spending $3.99 on salad dressing to have it be inedible once you try it. I seriously think that there should be like a tasting dispenser next to each bottle so you can try it and than decide to buy it or not. i'm not even going to get into my search for the perfect ranch; because i have found it but it's not purchasable, hello! Denny's. maybe my next business idea is to have a salad dressing store where you can taste before you buy, like a salad dressing sephora. yesssss, i can see the business plan now! anybody want to invest?
