Subway in Birmingham

If I could give a zero rating i would!. I asked about breakfast subs and meal deals as none of these items were being advertised in store. The price of the Egg and cheese breakfast sub started at " i think its £2.10 or maybe £2.20 and by the time we got to the till it was "oh, sorry its actually £2.50 and 10p extra for a bag" . The lady just made up her prices as she went along, awful customer service !
