Marion, I hate to say it but often times, the more you post about something, the more ‘snooty’ you appear.
In this case, I’d just quit while you are behind rather than continuing to dig.
You have to bag your own groceries? OH THE HUMANITY!!! What next, you have to actually take items off the shelf yourself and put them in your cart?!
I’d suggest that if you are so averse to ‘the poor’ that you just take advantage of the web grocery services and have your groceries delivered so you don’t have to rub elbows with the ‘those’ folks. It costs a little more but, after all, you’re worth it.
