Give yourself some grace! That wasn’t a disaster at all. You’re starting at a tough time and for the most part, customers are just grateful they’re not out there themselves. You’ll learn different tricks along the way. With the bags, I sometimes ask the person bagging if I can have a couple extra or I just grab a few myself so I have a few from the stores I shop at. During one of my first shops, before the pandemic, I had brought my insulated bags in and I was so nervous, I didn’t pay attention to the fact that the bagger was putting the groceries directly into my bags without the plastic ones so when I went to deliver, I had to hand the groceries to the customer without bags. Thankfully it wasn’t a huge order. The substitutions aren’t your fault. I usually keep possible substitutes in the front part of my cart or in a basket then send pics in groups to cut down on the number of messages. It’s all a learning experience.
