Earlier quoted context omitted.
That $1400/month number strikes me as dubious. They mention the charger earns $30-50/day. Assuming a standard 22-day work month, $1400 would have to be $63/day. A more realistic number seems to be $40 * 22 days, or $880/month. Which is not a lot of money in the expensive cities Lime is active in.
They were active in at least one Midwest city (Indianapolis) until last week, so $880 might not be a full-time job there, but would be a very nice supplementary income.
