seriously serious

Did you wake a day finding out that a habit that u do is simply without a shown purpose that u do it automaticly without meaning ?
and people knows that and laugh at you because of this habit

i had mainly three habits that i really dont know why do i do them

#1 when i buy my fav, stuff such as my spcial green tea or nespresso capsules or my red tea (addicted to caffine i know) when it strated to finish i bought a new box of tea or more capsules i mean by start to finish that there is one more box i dont like to see one box imagine !!

#2 when i go shopping i tend to buy 2 item of anything i buy i dont like to buy one only !! buy what u need only .

#3 change issue : when i pay for gas , reasaurant,cafe or even supermarket i dont like te change i like to pay like kd 3 or kd 5 without the 950 fils i really hate this number althogh it is a marketing issue

so guys is it noramal to do what i do or its a problem i need to be assitent with pros ??
