Domino's suffered noticeably during the pandemic lockdowns while the app-delivery services were eating their lunch, literally.
I live in a huge college town, so my delivery options nearby are nearly endless, with an amazing diversity of ethnic foods, mostly the type enjoyed by foreign students.
Domino's has always had a really good web interface and tracker. Unfortunately, since their business contracted, they actually closed their location nearest to campus (which was also nearest to me) and I'm not sure just how much consolidation that involved citywide, but their service was slow and bad after that. At least once, I never received a product after their tracker reported a successful delivery.
Refund requests are arduous and on the level of "don't even bother". Compare this to the way I could snap my fingers and get a GrubHub CSR to refund anything and everything.
There is another, independent pizza place with their own cadre of drivers, and they have fantastic service, they're open 24 hours, and they exhibit care and concern for my well-being. They always remark if they haven't seen/heard from me in a while. They never mess up my orders. Therefore I give them preference before I resort to any third-party app.
But it may also be that people have soured on delivery in general thanks to high fees charged by apps.
