Asking staff to rinse toddler plate

[leggingsandasweatshirt]

I am extremely hormonal so potentially being unreasonable, but interested to see if others think this is a reasonable request or if I am over stepping:

We were out for lunch today and I brought a suction plate for DS (almost 2) because he is likely to launch a regular plate. When we'd finished I realised I'd run out of nappy bags so didn't have anything to put the dirty plate in inside my bag.

I explained this to the waitress and apologised for being a pain and asked if it was possible for someone to give it a quick rinse so I could put it in my bag without covering everything in gravy.

She looked at me like I'd just shit on the table and responded she was trying to clear the plates. I was mortified that I had clearly offended her and said it didn't matter. My step mum then suggested I rinse the plate in the sink in the toilet which I hadn't thought of, so I then went and did that.

I have asked restaurants to do this on occasion before - am I being an entitled wanker or is this a reasonable request?!

I often work in restaurants and coffee shops on their machinery. I'm pretty sure any member of staff who responded like that would be disciplined. Your request was a basic level of customer service.

I go with slightly entitled but not enough to dwell on.....
If I were in the waitresses place I'd probably do it without thought...but..
In your place I wouldn't have asked (in my mind my kid my plate my mess)

So YANBU VS YANBU
