When you are packing food for a picnic, place cold food in a cooler with plenty of ice or commercial freezing gels.

当您为野餐包装食品时，把冷的食物放在一个有大量的冰的冷却器或商业冻结凝胶中。

I worry about making it on time through the airport, so I throw caution to the winds and pay for overpriced food rather than packing a picnic ahead of time.

我担心能否按时通过机场大约在，所以我把精力放在付更高的商品费用，而不是装备好随身物品。
