Intolerant people

So i was at this mini mart and this AUNTY was buying groceries and she was ahead of me at the cashier. the cashier scanned her items in and aunty walked away to take an item frm the shelf. so ok, nvm...she placed the item on the counter which the cashier proceeded to scan. then AUNTY decided she forgot some sanitary napkins & proceeded to walk to the back of the mini mart to get them & shop around while the cashier was stuck with her purchase, unable to cancel, unable to continue as the line got longer.

HALO AUNTY....like that everytime we walk in we give the cashier something to scan to book our place in line first la can?
