Beyond Infinity Two Minutes

In an ordinary coffee shop, the owner returned to his residence on the second floor after closing. When he was relaxing, he was suddenly called by himself on the computer screen. The other party claimed to be from himself two minutes later. It turns out there is a two-minute "time difference" between his coffee shop and his residence. As store clerks and regular customers join in for verification one after another, they are not only curious about their future selves, but also try to extend the two-minute time difference so that they have more time to foresee trends and prosper. But I never expected that the unbearable reversal of reality would lead to unexpected disasters.
