Do you use the self serve checkouts?

Many of us older people are retired and supplementing their retirement. Besides the fact we are often the only option for employees, companies are happy to have them. Us older people will show up, do our job, and are not dependent on benefits, just to name a few of our qualities.
My social security pays my rent, utility bills, internet, but during the month you still need to by food, gasoline, car insurance, and all the other things that society has forced upon us.
Us old guys, sometimes work a part time job to support SS benefits, or to have something to do.
My retirement savings comes from bailing out of muscle cars when the bailing was good.
Now i still tinker around with rebuilding of suspension, and brake parts, to help out the retirement savings, in this day and age.
