Cheap prices, poor service
One of the biggest problems with competing on price is you rarely have enough capital to incentivize your people.
Not just to hire great leaders who know better, but frontline staff who are eager to learn and to grow and to care.
That when people don't have a social incentive to perform at their best, let alone a financial reason to do so, there's little reason to expect that they will.
That's why cheap, mediocre brands never amount to much, despite always making enough money to stay afloat. There's a revolving door of customers more than willing to pay the least they can afford, but because their employees rarely stick around, they never have enough internal stability to grow.
What's left is a false front. A heavily marketed brand image without a community of people to epitomize it.
