I had a funny experience today with a MBO, which showed me you have to be very precise
Went for grocery shopping and when I was done I saw the long lines and I went into one even though I was third in that line, guy No 1 had loads and loads of groceries so I requested a MBO for another cashier to open ...About 2 mins later just when I started to put my groceries on the belt I heard a lady saying, come over here , I will open this cashier..My MBO was answered in no time but I should have added : ...another cashier to open so I can be first in line and can get out quickly
Here you go, be precise
