My friend has got into a habit of asking me to pick up things from the shop on the way to hers. This wouldn't be a problem except:
She messages me about 5 minutes before I'm due to arrive at hers. I'm driving (to hers), she would know that. I don't pick up messages while I'm driving. I have usually been to the shop on way to hers to pick up my food/drink contribution for the evening and then she unknowingly messages me after my shop run.
Her timings to ask me to get things is just dreadful. For example: I will have been to the shop on way to hers and got my bits. I get back into the car in The shop carpark to then receive a message from her with the things she wants. I then have to go back into shop. OR go to shop during the day to get my contributions for that eve. She messages me later in the day to ask me to pick up stuff on my way to her. I then have to decond shop run.
This is all stuff for our eve, food and drinks. I don't mind picking up her share (she gives me the cash) but I've usually done my shop run by the time she messages me. I'm running around going to the shop twice.
We both work FT. We both have DC and houses to run. I'm just more organised
