(117)Experience has shown that a series of other services, such as rescue services, firefighting services and prison services are normally only of cross-border interest as of such time as they acquire sufficient critical mass through their relatively high value. In so far as they are not excluded from the scope of this Directive, they should be included under light regime. To the extent that their provision is actually based on contracts, other categories of services, such as government services or the provision of services to the community, they would normally only be likely to present a cross-border interest as from a threshold of EUR 750 000 and should consequently only then be subject to the light regime.
