Coop Konsum Mariatorget! Be aware!!!

I was shopping for a client today at Coop Konsum Mariatorget and all of a sudden i saw a big black nasty roach running under the shelves!! I never ever saw 1 that big! I of course informed the staff! And they searches for it but without any result so please everyone go shop somewhere else or check your groceries carefully bcuz like most of us know , roaches is not to play with and hard to get away once they arrived! I certainly wish the staff or the Manager of the store take action Quickly!!!
