I'm quite surprised that I can't buy my bread with my restaurant tickets ... it's a staple! They are however accepted elsewhere ... moreover the security guards are not particularly friendly, on the contrary! I have a backpack so I'm a thief, of course! I always go shopping with my backpack and it never stops problem except in this Leclerc! And if unfortunately I come in without someone wrapping it in plastic for me then there ... I am being lectured! This store may be a stone's throw from my work place, but I would no longer buy my meal from them! It's the same story every time
