I think it is because gherkins are usually in an acid of some sort (vinegar) that would re-act with other containers.
Apparently, Mcdonald's put gherkins in their burger because their burgers contain so much sugar, if they didn't put the gherkins in the burgers, they would need to class them as desserts! Maybe this is the same reason everyone else puts gherkins in burgers!!
Pickled gherkins would not have a viscosity since viscosity refers to a liquid's resistance to flow.

In Europe, you will be served pickled gherkins with your burger.
The reason why McDonalds put gherkins in their burgers is because, with you the gherkins, the burgers would be classed as a dessert due to the high levels of sugar in their burgers.
No absolutely not. Contain a huge amount of sodium and phosphates.
Some people refer to pickled gherkins as wallies because this was a commonly used slang term in London. Wallies was a word that was commonly used in London in the 19th century.
