This pleasant light comedy is fairly amusing, and it is also rather engaging at times. It's simple in concept and in execution, and it's not uproarious or anything of the sort, but instead is an early, simple example of the kind of dry humor that is based on human nature itself, rather than on action or on humorous predicaments.
The whole scenario features a rather elderly couple sitting outside an art exhibit, having a snack before going in. The wife seems to get just a little impatient with her husband, suggesting the title phrase. Nothing fancy or complicated arises, but a couple of little touches work pretty well in creating some light humor.
As with most of the earliest narrative features, the main task of the film-makers was to create a setting and a camera field that could accommodate as much as possible. In this case, they set things up so as to create a view not only of the main couple, but also of enough of their surroundings (in particular, the signs in the background) so as to provide a complete picture of the situation. It also accommodates a couple of other characters who appear briefly.
It's all put together well enough to make pretty good use out of the main idea.
