Last week it was my Son's birthday and we planned to take the kids for a picnic to the lakeside park. We decided to make a salad and pack some sandwiches & drinks for the picnic. We prepared the sandwiches at night and took along with us for the morning trip. By mid-day we were at the lake. As we spread the sheets on the grass the kids felt hungry and demanding food. As I opened the basket I smelt something weird. The sandwiches with chicken filling was giving out unpleasant smell.
