I asked my sister for a favour

[MrsDeathOfRats]

I asked my sister if she would collect an order if I ordered it to store for me. There is no store near me and I didn't want to pay the delivery charge. I asked prior to ordering and she said yes.

I ordered the items and it has been sitting in the store since Monday. She had a day off yesterday but didn't go. She forgot to do it before work today and will either need to use her break but is unhappy as that will take up her whole break or will have to be at the store at 9am tomorrow, then leg it to her work place as she starts at 9.30.

She is basically in a right mood with me about it.

AIBU expecting her to use her break to go collect it?

Sounds like she didn't really think it through before volunteering - as such she hasn't got a leg to stand on! She may be annoyed but it's her own fault for agreeing to it.

She shouldn't have agreed if she wasn't willing to do the favour. You are definitely NBU.

YANBU. She agreed to help you out.

Thanks. Glad you agree with me and I'm not BU!
