Even if you dont ask for it! One time I just got done ordering my sandwich, they grab the mayo bottle and say "you want mayo?" Then jizz out half the bottle all over it before I can say no.
I don't get the mayonnaise hate. I know us white people put it on everything, but it's literally eggs, vinegar, oil, sometimes mustard... I love all of those!
People grow up on the shit tasting commercial crap or (shudders) Miracle Whip and then think all mayo tastes like it
I myself as a younger child fell into this and didn't really like Mayo until my preteen years when I realized that there's actually good tasting mayo out there
I like to make my own because it's quick, easy, and much tastier than most store bought, but I also understand that not everyone has an immersion blender or the desire for one.
I like to add fresh herbs to mine. A little dill or parsley really livens it up. I've tried mixing them in store bought and it's not the same.
