I would have replied, “leave them forever!”
They'd be in the bin for me as well mate. Some people have no fathom of how it can mess your day up and that you're trying to earn a living. I had one postpone on Tuesday as "we are are away on holiday, can you come at a later date?". I said no problem. Later on Tuesday I was walking out of the shop on the high street and she walked in. She went absolutely bright red with embarrassment. I just said "oh, hello" and carried on. A couple of years ago I had the "it upsets the dog too much". The dog was an absolute pain in the a*se . He used to come out of a dog flap and thought nothing of trying to chew the pole hose or p*ss all over anything and everything. Felt sorry for him as obviously he didn't have enough care taken after him.
Yes, we all get the silly excuses. What I do is not clean them again then usually after a few months they'll phone me up wondering where I've been. I'll reply that I thought they weren't keen on having them done anymore but didn't know how to tell me, which lets them know their excuse was a poor one. I find this acts as a sort of reset, the excuses stop or become much less frequent.
Based on this, I'd either drop her or skip the next clean and see what they say, being curt as she was and going back into the house isn't on in my books, it was a pish poor excuse it was foggy the next day so unless the car was garaged a few drops of water or overspray from you wouldn't have made any difference at all.
