I had that happen to me once. Last winter (keep in mind winter in Arizona is around 60 degrees) I went to Starbucks and I brought my dog. I left her in the car long enough to get my coffee and then I was going to get Missy and sit on the front patio with her. Then the girl at the counter asks where my dog is and I say she's in the car, I'm going to get her out once I get my my drink. And she yelled at me saying "don't you know you can't leave dogs in the car". And I was just like "well, in the summer you can't leave them in the car and you can't leave them for an extended period of time, but 5 minutes in the middle of January should be fine." But I couldn't beleive that she was yelling at me for that. I mean what else did she want me to do? I was going to tie her up outside on some post with her short leash. Where strangers could possibly do things to her.
