Someone else. A printer was bought some time in the past from a shop and its warranty was expiring soon, however it stopped working before that happened and it was sent for repairs 3 times in that time period. I was present at the third visit. The salesperson at the counter was a young fellow, probably new, who gave the regular spiel about sending it into service. The answer to that was "No. I already sent it two times and nothing was fixed. Call the manager." Manager showed up with "Sorry sir, not our fault. It all depends on our affiliated service repair. Blah, blah, blah." The reply to this bs was something like " 3 months ago I brought in the printer for repairs for the first time. You kept it for two weeks, said it worked fine and gave it back. It wasn't. I brought it back again and you saw for yourself it didn't work, so you took it again and kept it for a month. Now that the warranty is about to expire, you wanna keep it for two months and then give me back a piece of worthless trash? Do I look that dumb to you, son?"

Now i'm definitely misremembering the details, but it eventually climaxed with a threat of calling the relevant consumer protection agency, then the manager backing down and offering to replace the printer with a newer, different model for free.

That newer model worked for one more year after its renewed warranty expired and no one visited that shop ever again since. The end.
