wet public

I live on a canal boat in England. I’m diapered now, and looking for some humiliating tasks to do. Note I will not be exposing my diaper unless completely alone, but give me some ideas

I went to the post office in town and stood in a que for 45mins needless to say i used my diaper, then went to toilet only to realise i left my change at home.By the time i got into my car i was well soaked and as i sat down i felt the pee rise in my diaper and sufferd side leakage. I wasnt happy:(
