It'd depend on the circumstances when you're doing it but in general, I wouldn't find it disgusting, I'd just say it wouldn't be encouraged in certain circumstances. For example, suppose you're at a 5-star restaurant and with some very important clientele. In that case, I wouldn't view it as being an appropriate time but if you're at a small, clean, half-filled little truck-stop restaurant, then it may be more appropriate there. I'm not against it in public all the time, just in certain circumstances I think it should be done a bit later or elsewhere. Also, if you don't purposely let others see more boob than need be, such as flaunting it, then it's fine also.
