As a regular customer of Ladbrokes land based operations, I am very familiar with the myriad of coupons they have on offer from week to week.
A punter who is capable of formulating an accumulator wager should really be asking the question if special bets can be added to doubles upwards.
For instance anybody who has ever placed a football bet will be aware that some matches are not allowed as singles, minimum trebles upwards accepted. It is clearly marked on the coupon. However problems only begin to surface when the punter starts using regular betting slips, as he may not be aware of the rules. It is entirely the customers responsibility to educate himself upon the rules.
Weather bets are deemed special bets, the same as political bets and entertainment bets such as who will win the Xfactor. These are unique bets which cannot even be cross doubled with another special bet.
By the sounds of things this customer made a genuine error, which has cost him dearly. The customer by adding the weather bet to an accumulator did not obtain an odds advantage, the odds were not long odds on, they were odds against, the event happened, BUT he broke the rules. A very basic rule at that. Punters who are gambling in betting shops should really learn the basics, before they start tackling complex wagers.
I have seen many people in betting shops who try to play the system to their advantage, like marking Xs in the middle of a football coupon or scrawny writing that could be one of 2 horses running that day and piling loads of bets onto 1 slip so it can be disputed either way.
Ideally in this particular case the bet should be split into 2 separate bets. 1 single for the weather bet, and 1 fully permed accumulator for the bets that are left. This is how the original bet should have been made.
This is the solution I envisage Ladbrokes will offer the customer as a gesture of good will and to be seen to be fair.
