This drive me nuts around Grafton/Dawson Street. Students paying for a 4 euro lunch or coffee with a debit card, ffs. Queue takes forever and eats into my lunch break.Fucking Lidl..don't get me wrong - I love Lidl and Aldi for that matter. Its the people in front ..always with their fucking debit cards. Never cash in hand and only two or three items. Thats what pisses me off. Surely in this day of Playstation 4, Occulus Rift, Holidays in space etc etc they can speed up the poxy process. Is that too much to ask for!!??
