Those lines are definitely looking like half time , notice Man City vs South hampton over 1/1.5, and low scoring games such as Hull and Crystal Palace where you wouldn't expect much goals in the first half are set at over .5/1.
Don't fuk with your bookie, ask him if this is full time, because I see this as If you win, he finds out his mistake and doesn't pay out, if you lose he keeps your money.
