Embarrassed for recommending a Starbucks drink

So recently, I always order this brown sugar soymilk iced shaken espresso at my usual Starbucks, sobrang sarap nya. Then one time, I was with my colleagues, we were buying coffee at Starbucks (ibang branch), they asked me what I recommend, so I said the brown sugar... Hindi sila nasarapan hahaha. Then yesterday I got the same drink from a different branch, iba ang lasa, not as good as the one from my usual go to branch. Today I ordered the same from a different branch naman, iba din ang timpla. Huhu whyyy? Hindi ba isang recipe lang yun, bakit iba iba ang lasa? Kaya pala hindi sila nasarapan kasi iba pala ang lasa 😂
