Dog self service washes- opinions please!!

[fikel]

Have any of you had experience of self service dog washes, that are popular in the US, NZ and Oz?
You can choose what programme you require, including shampoo, conditioner, blow dry and even flea treatment. Would you use it say you had been to the park before putting doggie in the car, or instead of going to the groomers as would be a lot cheaper. Thanks in advance

There's one fairly near me on the south coast at the beach - I keep meaning to try it, I'm sure it will be easier than leaning over the bath, trying to wash her with the shower head while she attempts to jump over the sides..... Wish there were more about so there are closer ones
