If you have a small dog, a larger, “crazy dog” with anxiety issues can tear it to shreds. Fast.
Wait till your husband witnesses a dog fight, because it’s brutal and short of killing/really injuring the dog winning…you need specific stuff on hand (a large piece of plywood or a shield) and knowledge of dog jaws and how they pull, shake and tear animals and then you while killing/attacking to do anything.
Fast food employees are timed by the system: from the moment and order is place to the order is picked up. They are written up and penalized if it takes too long, no matter how short staffed they are. If they had unlocked the door, they’d have to answer walk-in questions that are easily answered by the sign, and they couldn’t help you without being fired anyhow.
