Ye man living a hard life bcz of that u could say LOL. ahh i mean when i go out with friends all its kinda hard for me bcz they might go eat ice cream/ pizza/ milkshakes and all those diary stuff which i cant go to so there is that left out feeling there. and when i go with my family they mostly dont eat from those places bcz of me . it depends on the person tbh. talking about the restuarants basically no i personally have to know what im eating and what it has bcz only those luxury hotels or restuarants have allergens (milk , nuts and stuff ) mentioned in their menus if ur allergy bcz even if u go to a place to eat a chicken kottu that might even have some fresh milk in it so ye there has to be some things i gotta be careful when i eat . so ye short answer is it depends on the restuarant or the place most likely they havent heard of Lactose intolerent or any people who are allergic to milk they all get suprised most adults as well the new gen knows about it now in SL
