Are Americans losing their taste for Starbucks? "The whole concept got old," one customer said.

Americans are addicted to caffeine but not to Starbucks, it seems.

When Chicago writer Natalia Nebel steps out for an espresso, for instance, Starbucks no longer comes to mind, even though she lives within walking distance to two of the coffee chain's more than 17,000 U.S. stores. 

"I used to go all the time and now I don't go anymore," said Nebel, 61, recalling her pre-COVID routine of setting up shop four days a week at a local Starbucks, finding it an enjoyable change of scenery and a comfortable spot to work. "I liked being around people in a different setting," Nebel told CBS MoneyWatch.
